Features

Description

• Input offset voltage 0.7 mV

• Input bias current 30 nA

• Input offset current 1.5 nA

• Full frequency compensation 30pF

• Supply voltage ±5.0V to ±20V

The LM101A/LH2101A is a general purpose high perfor-

mance operational ampliﬁer fabricated monolithically on a

silicon chip by an advanced epitaxial process. The LH2101A

consists of two LM101A ICs in one 16-lead DIP. The units

may be fully compensated with the addition of a 30 pF

capacitor stabilizing the circuit for all feedback conﬁgura-

tions including capacitive loads.

The device may be operated as a comparator with a differen-

tial input as high as 30V. Used as a comparator the output

can be clamped at any desired level to make it compatible

with logic circuits.

The LM101A and LH2101A operate over the full military

temperature range from -55°C to +125°C.

1. The inputs are shunted with back-to-back diodes for overvoltage protection. Therefore, if a differential input voltage in excess

of 1V is applied between the inputs, excessive current will flow, unless some limiting resistance is provided.

2. For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.

PRODUCT SPECIFICATION

cleaning procedure is required to achieve the LM108A’s

rated performance. It is suggested that board leakage be

minimized by encircling the input pins with a guard ring

maintained at a potential close to that of the inputs. The

guard ring should be driven by a low impedance source such

as an ampliﬁer’s output or ground.

Typical Applications

The LM108 series has very low input offset and bias

currents; the user is cautioned that printed circuit board

leakages can produce signiﬁcant errors especially at high

board temperatures. Careful attention to board layout and

Features

Description

• Large DC voltage gain—100 dB

• Compatible with all forms of logic

• Temperature compensated

• Unity Gain Bandwidth—1 MHz

• Large output voltage swing—0V to (+V -1.5V)

S

Each of the devices in this series consists of four indepen-

dent high-gain operational ampliﬁers that are designed for

single-supply operation. Operation from split power supplies

is also possible and the low power supply drain is indepen-

dent of the magnitude of the power supply voltage.

• Input common mode voltage range includes ground

Used with a dual supply, the circuit will operate over a wide

range of supply voltages. However, a large amount of cross-

over distortion may occur with loads to ground. An external

current-sinking resistor to -V will reduce crossover distor-

S

tion. There is no crossover distortion problem in

single-supply operation if the load is direct-coupled to

ground.

Notes:

1. Short circuits from the output to +V can cause excessive heating and eventual destruction. The maximum output current is

S

approximately 40 mA independent of the magnitude of +V . At values of supply voltage in excess d +V , continuous short

S

circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from

simultaneous shorts on all amplifiers.

2. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base

junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this

diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output

voltages of the op amps to go to the +V voltage level (or to ground for a large overdrive) for the time duration that an input

S

is driven negative. This is not destructive and normal output states will re-establish when the input voltage again returns to a

value greater than 0.3V.

2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent

upper end of the common mode voltage range is +V -1.5V, but either or both inputs can go to +32V without damage.

4. Due to proximity of external components, ensure that coupling is not originating via stray capacitance between these externall

parts. This typically can be detected as this type of capacitance increases at higher frequencies.

Features

Description

• Input common mode voltage range includes ground

• Wide single supply voltage range—2V to 36V

• Output compatible with TTL, DTL, ECL, MOS and

CMOS logic systems

• Very low supply current drain (0.8 mA) independent of

supply voltage

These devices offer higher frequency operation and faster

switching than can be had from internally compensated

quad op amps. Intended for single supply applications, the

Darlington PNP input stage allows them to compare voltages

that include ground. The two stage common-emitter output

circuit provides gain and output sink capacity of 3.2 mA at

an output level of 400 mV. The output collector is left open,

permitting the designer to drive devices in the range of 2V to

36V.

They are intended for applications not needing response time

less than 1 ms, but demanding excellent op amp input param-

eters to offset voltage, current and bias current, to ensure

accurate comparison with a reference voltage.

1. Short circuits from the output to +V can cause excessive heating and eventual destruction. The maximum output current is

S

approximately 20 mA independent of the magnitude of +Vs.

2. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector base

junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this

diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output

voltage of the comparators to go to the +V voltage level (or to ground for a large overdrive) for the time duration that an input

S

is driven negative. This is not destructive and nominal output states will re-establish when the input voltage, which was neg-

ative, again returns to a value greater than -0.3V.

4. The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The

tained. See Typical Performance Characteristics section.

6. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the com-

mon mode range, the comparator will provide a proper output state. The low input voltage stage must not be less than -0.3V

(or 0.3V below the magnitude of the negative power supply, if used).

The LM1458 series are dual general purpose operational amplifiers,

having short circuits protected and require no external components for

frequency compensation.

High common mode voltage range and absence of “latch up" make

the LM1458 ideal for use as voltage followers.

The high gain and wide range of operating voltage provides superior

performance in integrator, summing amplifier and general feedback

applications.

Features

Description

• 741 op amp operating characteristics

• Low supply current drain—0.6 mA/ampliﬁer

• Class AB output stage—no crossover distortion

• Pin compatible with the LM124

• Low input offset voltage—1.0 mV

• Low input offset current—4.0 nA

• Low input bias current—30 nA

• Unity gain bandwidth—1.0 MHz

• Channel Separation—120 dB

• Input and output overload protection

The LM148 is a true quad 741. It consists of four

independent high-gain, internally compensated, low-power

operational ampliﬁers which have been designed to provide

functional characteristics identical to those of the familiar

741 operational ampliﬁer. In addition, the total supply

current for all four ampliﬁers is comparable to the supply

current of a single 741 type op amp. Other features include

input offset currents and input bias currents which are much

less than those of a standard 741. Also, excellent isolation

between ampliﬁers has been achieved by independently

biasing each ampliﬁer and using layout techniques which

minimize thermal coupling.

The LM148 can be used anywhere multiple 741 type

ampliﬁers are being used and in applications where ampliﬁer

matching or high packing density is required.

LM148

PRODUCT SPECIFICATION

The LM148 is short circuit protected to ground and supplies

continuously when only one of the four ampliﬁers is shorted.

If multiple shorts occur simultaneously, the unit can be

destroyed due to excessive power dissipation.

Applications Discussion

The LM148 low power quad operational ampliﬁer exhibits

performance comparable to the popular 741. Substitution

can therefore be made with no change in circuit behavior.

To assure stability and to minimize pickup, feedback resis-

tors should be placed close to the input to maximize the feed-

back pole frequency (a function of input to ground

capacitance). A good rule of thumb is that the feedback pole

frequency should be 6 times the operating -3.0B frequency.

If less, a lead capacitor should be placed between the output

and input.

The input characteristics of these devices allow differential

voltages which exceed the supplies. Output phase will be

correct as long as one of the inputs is within the operating

common mode range. If both exceed the negative limit, the

output will latch positive. Current limiting resistors should

be used on the inputs in case voltages become excessive.

When capacitive loading becomes much greater than 100pF,

a resistor should be placed between the output and feedback

connection in order to reduce phase shift.

Features

• No potentiometer required

• Grounded neutral fault detection

• Direct interface to SCR

• Meets UL943 standards

• Supply voltage derived from AC line—26V shunt

• Adjustable sensitivity

• 450 mA quiescent current

• Ideal for 120V or 220V systems

Description

The LM1851 is a controller for AC outlet ground fault

interrupters. These devices detect hazardous grounding con-

ditions (example: a pool of water and electrical equipment

connected to opposite phases of the AC line) in consumer

and industrial environments. The output of the IC triggers an

external SCR, which in turn opens a relay circuit breaker to

prevent a harmful or lethal shock.

to line noise. A special feature is found in circuitry that

rapidly resets the integrating timing capacitor in the event

that noise pulses introduce unwanted charging currents.

Also, ﬂip-ﬂop is included that ensures ﬁring of even a slow

circuit breaker relay on either half-cycle of the line voltage

when external full wave rectiﬁcation is used.

The application circuit can be conﬁgured to detect both

normal faults (hot wire to ground) and grounded neutral

faults.

Full advantage of the U.S. UL943 timing speciﬁcation is

taken to ensure maximum immunity to false triggering due

Functional Description

The voltage at the supply pin is clamped to +26V by the

internal shunt regulator D3. This shunt regulator also

generates an artiﬁcial ground voltage for the noninverting

input of A1 (shown as a +10V source). A1, Q1, and Q2 act a

a current mirror for fault current signals (which are derived

from an external transformer). When a fault signal is present,

the mirrored current charges the external timing capacitor

until its voltage exceeds the latch trigger threshold (typically

17.5V). When then this threshold is exceeded, the latch

resistor. If fault signals are present at the input of A1 (which

is held at virtual ground, +10V), one of the two current

mirrors in the feedback path of A1 (Q4 and Q5) will become

active, depending on which half-cycle the fault occurs.

This action will raise the voltage at V , switching I to a

SET

A full-wave rectiﬁer bridge and a 15k/2W resistor are used

to supply the dc power required by the IC. A 1 mF capacitor

at pin 8 is used to ﬁlter the ripple of the supply voltage and is

also connected across the SCR to allow ﬁring of the SCR on

either half-cycle. When a fault causes the SCR to trigger, the

circuit breaker is energized and line voltage is removed from

the load.

Independent of setting sensitivity, the desired integration

time can be obtained through proper selection of the timing

capacitor, C . Due to the large number of variables involved,

T

proper selection of C is best done empirically. The follow-

T

ing design example should only be used as a guideline.

At this time no fault current ﬂows and the C discharge cur-

rent increases from I to 3I (see Block Diagram). This

The circuit breaker can be reset and the line voltage again

supplied to the load, assuming the fault has been removed. A

1000:1 sense transformer is used to detect the normal fault.

The fault current, which is basically the difference current

between the got and neutral lines, is stepped down by 1000

and fed into the input pin of the operational ampliﬁer

through a 10 mF capacitor. The 0.0033 mF capacitor between

pin 2 and pin 3 and the 200 pF between pins 3 and 4 are

added to obtain better noise immunity. The normal fault sen-

sitivity is determined by the timing capacitor discharging

Programmable Video Sync Generator

’ACT715-R/LM1882-R is mask programmed to default to a

Clock Enabled state. Bit 10 of the Status Register defaults

to a logic ‘‘1’’. Although completely (re)programmable, the

’ACT715-R/LM1882-R version is better suited for applica-

tions using the default 14.31818 MHz RS-170 register val-

ues. This feature allows power-up directly into operation,

following a single CLEAR pulse.

General Description

The ’ACT715/LM1882 and ’ACT715-R/LM1882-R are

20-pin TTL-input compatible devices capable of generating

Horizontal, Vertical and Composite Sync and Blank signals

for televisions and monitors. All pulse widths are completely

definable by the user. The devices are capable of generat-

ing signals for both interlaced and noninterlaced modes of

operation. Equalization and serration pulses can be intro-

duced into the Composite Sync signal when needed.

Features

Y

l

130 MHz

Maximum Input Clock Frequency

Four additional signals can also be made available when

Composite Sync or Blank are used. These signals can be

used to generate horizontal or vertical gating pulses, cursor

position or vertical Interrupt signal.

Interlaced and non-interlaced formats available

Separate or composite horizontal and vertical Sync and

Blank signals available

Y

Complete control of pulse width via register

programming

These devices make no assumptions concerning the sys-

tem architecture. Line rate and field/frame rate are all a

function of the values programmed into the data registers,

the status register, and the input clock frequency.

Y

All inputs are TTL compatible

8 mA drive on all outputs

Default RS170/NTSC values mask programmed into

registers

The ’ACT715/LM1882 is mask programmed to default to a

Clock Disable state. Bit 10 of the Status Register, Register

0, defaults to a logic ‘‘0’’. This facilitates (re)programming

before operation.

Y

a

Total of 13 inputs and

5

outputs on the

ODD/EVEN: Output that identifies if display is in odd (HIGH)

or even (LOW) field of interlace when device is in interlaced

mode of operation. In noninterlaced mode of operation this

output is always HIGH. Data can be serially scanned out on

this pin during Scan Mode.

Data Inputs D0–D7: The Data Input pins connect to the

Address Register and the Data Input Register.

ADDR/DATA: The ADDR/DATA signal is latched into the

device on the falling edge of the LOAD signal. The signal

determines if an address (0) or data (1) is present on the

data bus.

VCSYNC: Outputs Vertical or Composite Sync signal based

on value of the Status Register. Equalization and Serration

pulses will (if enabled) be output on the VCSYNC signal in

composite mode only.

L/HBYTE: The L/HBYTE signal is latched into the device

on the falling edge of the LOAD signal. The signal deter-

mines if data will be read into the 8 LSB’s (0) or the 4 MSB’s

(1) of the Data Registers. A 1 on this pin when an ADDR/

DATA is a 0 enables Auto-Load Mode.

VCBLANK: Outputs Vertical or Composite Blanking signal

based on value of the Status Register.

HBLHDR: Outputs Horizontal Blanking signal, Horizontal

Gating signal or Cursor Position based on value of the

Status Register.

LOAD: The LOAD control pin loads data into the Address or

Data Registers on the rising edge. ADDR/DATA and

L/HBYTE data is loaded into the device on the falling edge

of the LOAD. The LOAD pin has been implemented as a

Schmitt trigger input for better noise immunity.

HSYNVDR: Outputs Horizontal Sync signal, Vertical Gating

signal or Vertical Interrupt signal based on value of Status

Register.

Register Description

CLOCK: System CLOCK input from which all timing is de-

rived. The clock pin has been implemented as a Schmitt

trigger for better noise immunity. The CLOCK and the LOAD

signal are asynchronous and independent. Output state

changes occur on the falling edge of CLOCK.

All of the data registers are 12 bits wide. Width’s of all puls-

es are defined by specifying the start count and end count

of all pulses. Horizontal pulses are specified with-respect-to

the number of clock pulses per line and vertical pulses are

specified with-respect-to the number of lines per frame.

CLR: The CLEAR pin is an asynchronous input that initializ-

es the device when it is HIGH. Initialization consists of set-

ting all registers to their mask programmed values, and ini-

tializing all counters, comparators and registers. The

CLEAR pin has been implemented as a Schmitt trigger for

better noise immunity. A CLEAR pulse should be asserted

by the user immediately after power-up to ensure proper

initialization of the registersÐeven if the user plans to

(re)program the device.

REG0ÐSTATUS REGISTER

The Status Register controls the mode of operation, the

signals that are output and the polarity of these outputs. The

default value for the Status Register is 0 (000 Hex) for the

’ACT715/LM1882 and is ‘‘512’’ (200 Hex) for the ’ACT715-

R/LM1882-R.

Note: A CLEAR pulse will disable the CLOCK on the ’ACT715/LM1882 and

will enable the CLOCK on the ’ACT715-R/LM1882-R.

Composite Sync and Blank signals are created by logically

ANDing (ORing) the active LOW (HIGH) signals of the cor-

responding vertical and horizontal components of these sig-

nals. The Composite Sync signal may also include serration

and/or equalization pulses. The Serration pulse interval oc-

curs in place of the Vertical Sync interval. Equalization puls-

es occur preceding and/or following the Serration pulses.

The width and location of these pulses can be programmed

through the registers shown below. (See Figure 2B.)

VERTICAL SYNC AND BLANK SPECIFICATION

All vertical signals are defined in terms of number of lines

per frame. This is true in both interlaced and noninterlaced

modes of operation. Care must be taken to not specify the

Vertical Registers in terms of lines per field. Since the first

Ý

CLOCK edge, CLOCK 1, causes the first falling edge of

the Vertical Blank (first Horizontal Blank) reference pulse,

a

edges referenced to this first edge are n

1 lines away,

where ‘‘n’’ is the width of the timing in question. Registers 5,

6, and 7 are programmed in this manner. Also, in the inter-

laced mode, vertical timing is based on half-lines. Therefore

registers 5, 6, and 7 must contain a value twice the total

horizontal (odd and even) plus 1 (as described above). In

non-interlaced mode, all vertical timing is based on whole-

lines. Register 8 is always based on whole-lines and does

not add 1 for the first clock. The vertical counter starts at

the value of 1 and counts until the value of VMAX. No re-

strictions exist on the values placed in the vertical registers.

Vertical Blank will change on the leading edge of HBLANK.

Vertical Sync will change on the leading edge of HSYNC.

and Bit 2 of the Status Register is set to the value of 1. The

Cursor Position generates a single pulse of n clocks wide

during every line that the cursor is specified. The signals are

generated by logically ORing (ANDing) the active LOW

(HIGH) signals specified by the registers used for generat-

ing Horizontal and Vertical Gating signals. The Vertical In-

terrupt signal generates a pulse during the vertical interval

specified. The Vertical Interrupt signal will change in the

same manner as that specified for the Vertical Blanking sig-

nal.

Horizontal Drive and Vertical Drive outputs can be utilized

as general purpose Gating Signals. Horizontal and Vertical

Addressing Logic

The register addressing logic is composed of two blocks of

logic. The first is the address register and counter

(ADDRCNTR), and the second is the address decode

(ADDRDEC).

time the High Byte is written the address counter is incre-

mented by 1. The counter has been implemented to loop on

the initial value loaded into the address register. For exam-

ple: If a value of 0 was written into the address register then

the counter would count from 0 to 18 before resetting back

to 0. If a value of 15 was written into the address register

then the counter would count from 15 to 18 before looping

back to 15. If a value greater than or equal to 18 is placed

into the address register the counter will continuously loop

on this value. Auto addressing is initiated on the falling edge

of LOAD when ADDRDATA is 0 and LHBYTE is 1. Incre-

menting and loading of data registers will not commence

until the falling edge of LOAD after ADDRDATA goes to 1.

The next rising edge of LOAD will load the first byte of data.

Auto Incrementing is disabled on the falling edge of LOAD

after ADDRDATA and LHBYTE goes low.

ADDRCNTR LOGIC

Addresses for the data registers can be generated by one of

two methods. Manual addressing requires that each byte of

each register that needs to be loaded needs to be ad-

dressed. To load both bytes of all 19 registers would require

a total of 57 load cycles (19 address and 38 data cycles).

Auto Addressing requires that only the initial register value

be specified. The Auto Load sequence would require only

39 load cycles to completely program all registers (1 ad-

dress and 38 data cycles). In the auto load sequence the

low order byte of the data register will be written first fol-

lowed by the high order byte on the next load cycle. At the

Addressing Logic (Continued)

ADDRDEC LOGIC

The ADDRDEC logic decodes the current address and gen-

erates the enable signal for the appropriate register. The

enable values for the registers and counters change on the

falling edge of LOAD. Two types of ADDRDEC logic is en-

abled by 2 pair of addresses, Addresses 22 or 54 (Vectored

Restart logic) and Addresses 23 or 55 (Vectored Clear log-

ic). Loading these addresses will enable the appropriate log-

ic and put the part into either a Restart (all counter registers

are reinitialized with preprogrammed data) or Clear (all reg-

isters are cleared to zero) state. Reloading the same

ADDRDEC address will not cause any change in the state of

the part. The outputs during these states are frozen and the

internal CLOCK is disabled. Clocking the part during a Vec-

tored Restart or Vectored Clear state will have no effect on

the part. To resume operation in the new state, or disable

the Vectored Restart or Vectored Clear state, another non-

ADDRDEC address must be loaded. Operation will begin in

the new state on the rising edge of the non-ADDRDEC load

pulse. It is recommended that an unused address be loaded

following an ADDRDEC operation to prevent data registers

from accidentally being corrupted. The following Addresses

are used by the device.

TL/F/10137–9

FIGURE 3. ADDRDEC Timing

GEN LOCKING

The ’ACT715/LM1882 and ’ACT715-R/LM1882-R is de-

signed for master SYNC and BLANK signal generation.

However, the devices can be synchronized (slaved) to an

external timing signal in a limited sense. Using Vectored

Restart, the user can reset the counting sequence to a giv-

en location, the beginning, at a given time, the rising edge of

the LOAD that removes Vector Restart. At this time the next

CLOCK pulse will be CLOCK 1 and the count will restart at

the beginning of the first odd line.

Address 0

Status Register REG0

Address 1–18 Data Registers REG1–REG18

Address 19–21 Unused

Address 22/54 Restart Vector (Restarts Device)

Address 23/55 Clear Vector (Zeros All Registers)

Address 24–31 Unused

Preconditioning the part during normal operation, before the

desired synchronizing pulse, is necesasry. However, since

LOAD and CLOCK are asynchronous and independent, this

is possible without interruption or data and performance cor-

ruption. If the defaulted 14.31818 MHz RS-170 values are

being used, preconditioning and restarting can be minimized

by using the CLEAR pulse instead of the Vectored Restart

operation. The ’ACT715-R/LM1882-R is better suited for

this application because it eliminates the need to program a

1 into Bit 10 of the Status Register to enable the CLOCK.

Gen Locking to another count location other than the very

beginning or separate horizontal/vertical resetting is not

possible with the ’ACT715/LM1882 nor the ’ACT715-R/

LM1882-R.

Address 32–50 Register Scan Addresses

Address 51–53 Counter Scan Addresses

Address 56–63 Unused

At any given time only one register at most is selected. It is

possible to have no registers selected.

VECTORED RESTART ADDRESS

The function of addresses 22 (16H) or 54 (36H) are similar

to that of the CLR pin except that the preprogramming of

the registers is not affected. It is recommended but not re-

quired that this address is read after the initial device config-

uration load sequence. A 1 on the ADDRDATA pin (Auto

Addressing Mode) will not cause this address to automati-

cally increment. The address will loop back onto itself re-

gardless of the state of ADDRDATA unless the address on

the Data inputs has been changed with ADDRDATA at 0.

SCAN MODE LOGIC

A scan mode is available in the ACT715/LM1882 that al-

lows the user to non-destructively verify the contents of the

registers. Scan mode is invoked through reading a scan ad-

dress into the address register. The scan address of a given

a

register is defined by the Data register address

32. The

VECTORED CLEAR ADDRESS

internal Clocking signal is disabled when a scan address is

read. Disabling the clock freezes the device in it’s present

state. Data can then be serially scanned out of the data

registers through the ODD/EVEN Pin. The LSB will be

scanned out first. Since each register is 12 bits wide, com-

pletely scanning out data of the addressed register will re-

quire 12 CLOCK pulses. More than 12 CLOCK pulses on the

same register will only cause the MSB to repeat on the out-

put. Re-scanning the same register will require that register

to be reloaded. The value of the two horizontal counters and

1 vertical counter can also be scanned out by using address

numbers 51–53. Note that before the part will scan out the

data, the LOAD signal must be brought back HIGH.

Addresses 23 (17H) or 55 (37H) is used to clear all registers

to zero simultaneously. This function may be desirable to

use prior to loading new data into the Data or Status Regis-

ters. This address is read into the device in a similar fashion

as all of the other registers. A 1 on the ADDRDATA pin

(Auto Addressing Mode) will not cause this address to auto-

matically increment. The address will loop back onto itself

regardless of the state of ADDRDATA unless the address

on the Data inputs has been changed with ADDRDATA at 0.

7

Addressing Logic (Continued)

Normal device operation can be resumed by loading in a

non-scan address. As the scanning of the registers is a non-

destructive scan, the device will resume correct operation

from the point at which it was halted.

POWERING UP

PREPROGRAMMING ‘‘ON-THE-FLY’’

The ’ACT715/LM1882 default value for Bit 10 of the Status

Register is 0. This means that when the CLEAR pulse is

applied and the registers are initialized by loading the de-

fault values the CLOCK is disabled. Before operation can

begin, Bit 10 must be changed to a 1 to enable CLOCK. If

the default values are needed (no other programming is re-

quired) thenFigure 5 illustrates a hardwired solution to facili-

tate the enabling of the CLOCK after power-up. Should con-

trol signals be difficult to obtain, Figure 6 illustrates a possi-

ble solution to automatically enable the CLOCK upon pow-

er-up. Use of the ’ACT715-R/LM1882-R eliminates the

need for most of this circuitry. Modifications of the Figure 6

circuit can be made to obtain the lone CLEAR pulse still

needed upon power-up.

Although the ’ACT715/LM1882 and ’ACT715-R/LM1882-R

are completely programmable, certain limitations must be

set as to when and how the parts can be reprogrammed.

Care must be taken when reprogramming any End Time

registers to a new value that is lower than the current value.

Should the reprogramming occur when the counters are at a

count after the new value but before the old value, then the

counters will continue to count up to 4096 before rolling

over.

For this reason one of the following two precautions are

recommended when reprogramming ‘‘on-the-fly’’. The first

recommendation is to reprogram horizontal values during

the horizontal blank interval only and/or vertical values dur-

ing the vertical blank interval only. Since this would require

delicate timing requirements the second recommendation

may be more appropriate.

Note that, although during a Vectored Restart none of the

preprogrammed registers are affected, some signals are af-

fected for the duration of one frame only. These signals are

the Horizontal and Vertical Drive signals. After a Vectored

Restart the beginning of these signals will occur at the first

CLK. The end of the signals will occur as programmed. At

the completion of the first frame, the signals will resume to

their programmed start and end time.

The second recommendation is to program a Vectored Re-

start as the final step of reprogramming. This will ensure

that all registers are set to the newly programmed values

and that all counters restart at the first CLK position. This

will avoid overrunning the counter end times and will main-

tain the video integrity.

LM336-2.5/B/LM236-2.5 (KA336-2.5, KA236-2.5) PROGRAMMABLE SHUNT REGULATOR

PROGRAMMABLE SHUNT REGULATOR

TO-92

The LM336-2.5/B integrated Circuits are precision 2.5V shunt

regulators. The monolithic IC voltage references operates as a low

temperature coefficient 2.5V zener with 0.2W dynamic impedance.

A third terminal on the KA336-2.5/B allow the reference voltage and

temperature coefficient to be trimmed easily.

LM3362.5/B are useful as a precision 2.5V low voltage reference for

digital voltmeters, power supplies or op amp circuitry. The 2.5V make

it convenient to obtain a stable reference from low voltage supplies.

Further, since the LM336-2.5/B operate as shunt regulators, they can

be used as either a positive or negative voltage reference.

LM248, LM348

QUAD OPERATIONAL AMPLIFIER

QUAD OPERATIONAL AMPLIFIERS

The LM248/LM348 is a true quad LM741. It consists of four independ-

ent, high-gain, internally compensated, low-power operational amplifiers

which have been designed to provide functional characteristics identical

to those of the familiar LM741 operational amplifier. In addition the total

supply current for all four amplifiers is comparable to the Supply current

of a single LM741 type OP Amp.

14 DIP

Other features include input offset currents and input bias current which

are much less than those of a standard LM741. Also, excellent isolation

between amplifiers has been achieved by independently biasing each

amplifier and using layout techniques which minimize thermal coupling.

DUAL OPERATIONAL AMPLIFIER

DUAL OPERATIONAL AMPLIFIERS

8 DIP

The LM258 series consists of four independent, high gain, internally

Frequency compensated operational amplifiers which were designed

specifically to operate from a single power supply over a wide range

of voltage.

Operation from split power supplies is also possible and the low power

Supply current drain is independent of the magnitude of the power Supply

voltage. Application areas include transducer amplifier, DC gain blocks and

all the conventional OP amp circuits which now can be easily implemented

in single 8 SOP power supply system.

FEATURES

·

Internally frequency compensated for unity gain

Large DC voltage gain: 100dB

Wide power supply range: LM258/A, LM358/A: 3V~32V (or ±1.5V~16V)

LM2904: 3V~26V (or ±1.5V~13V)

9 SIP

·

Input common-mode voltage range Includes ground

Large output voltage swing: 0V DC to Vcc - 1.5V DC

APPLICATION CIRCUIT

LM555/I

SINGLE TIMER

APPLICATION NOTE

The application circuit shows astable mode.

Pin 6 (threshold) is tied to Pin 2 (trigger) and Pin 4 (reset) is tied to V_CC(Pin 8).

The external capacitor C₁of Pin 6 and Pin 2 charges through R_A, R_Band discharges through R_Bonly.

In the internal circuit of the LM555 one input of the upper comparator is the 2/3 V_CC(*R₁=R₂=R_3,another input if it

If it is connected Pin 6.

As soon as charging C₁is higher than 2/3 Vcc, discharge transistor Q₁turns on and C₁discharges to collector of

transistor Q₁.

Therefore, the flip-flop circuit is reset and output is low.

One input of lower comparator is the 1/3 V_CC, discharge transistor Q₁turn off and C₁charges through R_Aand R_B.

Therefore, the flip-flop circuit is set and output is high.

So to say, when C₁charges through R_Aand R₁output is high and when C₁discharges through R_Boutput is low.

The charge time (output is high) T₁is 0.693 (R_A+R_B) C₁and the discharge time (output is low) T₂is 0.693 (R_BC₁).

V_CC-1/3V_CC

V_CC-2/3V_CC

(I_n

= 0.693)

Thus the total period time T is given by

T=T₁+T₂= 0.693 (R_A+2R_B) C₁.

Then the frequency of astable mode is given by

Astable Operation

The LM555 can free run as a mulitivibrator by triggering itself; refer to Fig.2. The output can swing from V_DDto GND and have

Monostable Operation

The LM555 can be used as a one-short, i.e. monostable multivibrator. Initially, because the inside discharge transistor is on

state, external timing capacitor is held to GND potential. Upon application of a negative TRIGGER pulse pin 2, the intern

discharge transistor is off state and the voltage across the capacitor increases with time constant T = R_AC and OUTPUT

goes to high state. When the voltage across the capacitor equals 2/3V_CCthe inner comparator is reset by THRESHOLD

input and the discharge transistor goes to on state, which in turn discharges the capacitor rapidly and drives the OUTPUT

to its low state.

3-TERMINAL 1A POSITIVE

VOLTAGE REGULATORS

TO-220

The LM78XX series of three-terminal positive regulators are available in

the TO-220/D-PAK package and with several fixed output voltages, making

them useful in a wide range of applications. Each type employs internal

current limiting, thermal shut-down and safe area protection, making it

essentially indestructible. If adequate heat sinking is provided, they can

deliver over 1A output current. Although designed primarily as fixed voltage

D-PAK

regulators, these devices can be used with external components to obtain

adjustable voltages and currents.

Notes:

(1) To specify an output voltage. substitute voltage value for "XX."

A common ground is required between the input and the Output

voltage. The input voltage must remain typically 2.0V above the output

voltage even during the low point on the input ripple voltage.

(2) C_Iis required if regulator is located an appreciable distance from

power Supply filter.

(3) C_Oimproves stability and transient response.

MC79LXXA (LM79LXXA) (KA79LXXA)

FIXED VOLTAGE REGULATOR (NEGATIVE)

TYPICAL APPLICATIONS

Design Considerations

The MC79LXXA Series of fixed voltage regulators

are designed with Thermal Overload Protection that

shuts down the circuit when subjected to an excessive

power overload condition. Internal Short-Circuit

Protection that limits the maximum current the circuit

will pass.

In many low current applications, compensation

capacitors are not required. However, it is

recommended that the regulator input be bypassed

with a capacitor if the regulator is connected to the

power supply filter with long wire lengths, or if the

output load capacitance is large. An input bypass

capacitor should be selected to provide good high -

frequency characteristics to insure stable operation

under all load conditions. A 0.33mF or larger tantalum,

mylar, or other capacitor having low internal

impedance at high frequencies should be chosen. The

bypass capacitor should be mounted with the shortest

possible leads directly across the regulator's input

terminals. Normally good construction techniques

should be used to minimize ground loops and lead

resistance drops since the regulator has no external

sense lead. Bypassing the output is also

recommended.

Fig. 1 Positive And Negative Regulator

Fig. 2 Typical Application

OUTPUT

A common ground is required between the Input

and the output voltages. The input voltage must

remain typically 2.0V above the output voltage even

during the low point on the input ripple voltage.

= C₁is required if regulator is located an

appreciable distance from power supply filter.

* * = C_Oimproves stability and transient response.

LM79MXX

FIXED VOLTAGE REGULATOR(NEGATIVE)

TYPICAL APPLICATIONS

Bypass capacitors are recommended for stable operation of the KA79MXX series of regulators over the input voltage and output

current ranges. Output bypass capacitors will improve the transient response of the regulator.

The bypass capacitors, (2mF on the input, 1mF on the output) should be ceramic or solid tantalum which have good high frequency

characteristics. If aluminum electronics are used, their values should be 10mF or larger. The bypass capacitors should be

mounted with the shortest leads, and if possible, directly across the regulator terminals.

Fig. 1 Fixed Output Regulator

Fig. 2 Variable Output

Note

1. Required for stability. For value given, capacitor must

be solid tantalum. 25mF aluminum electrolytic may

be substituted.

2. C₂improves transient response and ripple rejection.

Do not increase beyond 50mF.

KA79MXX

FIXED VOLTAGE REGULATOR(NEGATIVE)

TYPICAL APPLICATIONS

Bypass capacitors are recommended for stable operation of the KA79MXX series of regulators over the input voltage and output

current ranges. Output bypass capacitors will improve the transient response of the regulator.

The bypass capacitors, (2mF on the input, 1mF on the output) should be ceramic or solid tantalum which have good high frequency

characteristics. If aluminum electronics are used, their values should be 10mF or larger. The bypass capacitors should be

mounted with the shortest leads, and if possible, directly across the regulator terminals.

Fig. 2 Variable Output

Note

1. Required for stability. For value given, capacitor must

be solid tantalum. 25mF aluminum electrolytic may

be substituted.

2. C₂improves transient response and ripple rejection.

Do not increase beyond 50mF.
