Low Power Quad Operational Amplifiers

General Description

Advantages

The LM124/124A consists of four independent, high gain, in-

ternally frequency compensated operational amplifiers which

were designed specifically to operate from a single power

supply over a wide range of voltages. 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.

Eliminates need for dual supplies

■

Four internally compensated op amps in a single package

Allows directly sensing near GND and V_OUTalso goes to

GND

Compatible with all forms of logic

■

Power drain suitable for battery operation

Application areas include transducer amplifiers, DC gain

blocks and all the conventional op amp circuits which now can

be more easily implemented in single power supply systems.

For example, the LM124/124A can be directly operated off of

the standard +5Vdc power supply voltage which is used in

digital systems and will easily provide the required interface

electronics without requiring the additional +15Vdc power

supplies.

Unique Characteristics

Wide power supply range:

Single supply 3V to 32V

or dual supplies ±1.5V to ±16V

■

In the linear mode the input common-mode voltage range

■

includes ground and the output voltage can also swing to

ground, even though operated from only a single power

supply voltage

Very low supply current drain (700 μA)—essentially

■

independent of supply voltage

The unity gain cross frequency is temperature

compensated

■

Low input biasing current 45 nA

(temperature compensated)

Low input offset voltage 2 mV

and offset current: 5 nA

The input bias current is also temperature compensated

■

Input common-mode voltage range includes ground

■

Differential input voltage range equal to the power supply

voltage

Large output voltage swing 0V to V⁺− 1.5V

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed

specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test

conditions.

Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T_Jmax(maximum junction temperature), ThetaJ_A(package

junction to ambient thermal resistance), and T_A(ambient temperature). The maximum allowable power dissipation at any temperature is P_Dmax= (T_Jmax- T_A)/

ThetaJ_Aor the number given in the Absolute Maximum Ratings, whichever is lower.

Note 4: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum

output current is approximately 40mA independent of the magnitude of V+. At values of supply voltage in excess of +15V_DC, continuous short-circuits can exceed

the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.

Note 5: 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 is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again

returns to a value greater than -0.3V_DC(at 25°C).

Note 6: Human body model, 1.5 kΩ in series with 100 pF.

Note 7: Guaranteed by V_IOtests.

Note 8: Datalog reading in K=V/mV

Note 9: Guaranteed, not tested

Note 10: Calculated parameters

Note 11: Pre and post irradiation limits are identical to those listed under AC and DC electrical characteristics except as listed in the Post Radiation Limits Table.

These parts may be dose rate sensitive in a space environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters

are guaranteed only for the conditions as specified in MIL-STD-883, Method 1019

Note 12: Low dose rate testing has been performed on a wafer-by-wafer basis, per test method 1019 condition D of MIL-STD-883, with no enhanced low dose

rate sensitivity (ELDRS) effect.

Note 13: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output

so no loading change exists on the input lines.

Note 14: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The upper end of the

common-mode voltage range is V+ −1.5V (at 25°C), but either or both inputs can go to +32V without damage independent of the magnitude of V+.

Note 15: Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can

be detected as this type of capacitance increases at higher frequencies.

output of the amplifier to ground to increase the class A bias

current and prevent crossover distortion.

Application Hints

The LM124 series are op amps which operate with only a

single power supply voltage, have true-differential inputs, and

remain in the linear mode with an input common-mode volt-

age of 0 V_DC. These amplifiers operate over a wide range of

power supply voltage with little change in performance char-

acteristics. At 25°C amplifier operation is possible down to a

Where the load is directly coupled, as in dc applications, there

is no crossover distortion.

Capacitive loads which are applied directly to the output of the

amplifier reduce the loop stability margin. Values of 50 pF can

be accommodated using the worst-case non-inverting unity

gain connection. Large closed loop gains or resistive isolation

should be used if larger load capacitance must be driven by

the amplifier.

minimum supply voltage of 2.3 V_DC

The pinouts of the package have been designed to simplify

PC board layouts. Inverting inputs are adjacent to outputs for

all of the amplifiers and the outputs have also been placed at

the corners of the package (pins 1, 7, 8, and 14).

The bias network of the LM124 establishes a drain current

which is independent of the magnitude of the power supply

voltage over the range of from 3 V_DCto 30 V_DC

Precautions should be taken to insure that the power supply

for the integrated circuit never becomes reversed in polarity

or that the unit is not inadvertently installed backwards in a

test socket as an unlimited current surge through the resulting

forward diode within the IC could cause fusing of the internal

conductors and result in a destroyed unit.

Output short circuits either to ground or to the positive power

supply should be of short time duration. Units can be de-

stroyed, not as a result of the short circuit current causing

metal fusing, but rather due to the large increase in IC chip

dissipation which will cause eventual failure due to excessive

junction temperatures. Putting direct short-circuits on more

than one amplifier at a time will increase the total IC power

dissipation to destructive levels, if not properly protected with

external dissipation limiting resistors in series with the output

leads of the amplifiers. The larger value of output source cur-

rent which is available at 25°C provides a larger output current

capability at elevated temperatures (see typical performance

characteristics) than a standard IC op amp.

Large differential input voltages can be easily accommodated

and, as input differential voltage protection diodes are not

needed, no large input currents result from large differential

input voltages. The differential input voltage may be larger

than V⁺without damaging the device. Protection should be

provided to prevent the input voltages from going negative

more than −0.3 V_DC(at 25°C). An input clamp diode with a

resistor to the IC input terminal can be used.

The circuits presented in the section on typical applications

emphasize operation on only a single power supply voltage.

If complementary power supplies are available, all of the stan-

dard op amp circuits can be used. In general, introducing a

pseudo-ground (a bias voltage reference of V⁺/2) will allow

operation above and below this value in single power supply

systems. Many application circuits are shown which take ad-

vantage of the wide input common-mode voltage range which

includes ground. In most cases, input biasing is not required

and input voltages which range to ground can easily be ac-

commodated.

To reduce the power supply drain, the amplifiers have a class

A output stage for small signal levels which converts to class

B in a large signal mode. This allows the amplifiers to both

source and sink large output currents. Therefore both NPN

and PNP external current boost transistors can be used to

extend the power capability of the basic amplifiers. The output

voltage needs to raise approximately 1 diode drop above

ground to bias the on-chip vertical PNP transistor for output

current sinking applications.

For ac applications, where the load is capacitively coupled to

the output of the amplifier, a resistor should be used, from the
