DESCRIPTION

The SP8528 is a very low power 12-Bit A/D converter. The SP8528 typically draws 230µA of

supply current when sampling at 33.2 kHz. Supply current drops linearly as the sample rate is

reduced. The ADC automatically powers down when not performing conversions, drawing only

leakage current. The SP8528 is available in 8-Pin NSOIC packages, specified over Commercial

and Industrial temperature ranges. The SP8528 is best suited for Battery-Operated Systems,

Portable Data Acquisition Instrumentation, Battery Monitoring, and Remote Sensing

applications. The serial port allows efficient data transfer to a wide range of microprocessors and

microcontrollers over 3 wires.

DESCRIPTION

The device features automatic shutdown and

will shutdown to a +0.5 µA power level as CS

is brought high (de-selected). Power is proportional

to conversion duty cycle and varies from 230

µA at 30.1 µS (Duty cycle = 100%) to

5.75 µA at 1.2 ms (Duty cycle = 2.5%).

The SP8528 is a 12 bit full differential sampling

ADC with a serial data interface. The ADC

samples and converts 12 bits of data in 30.1 µS

with a 5V supply voltage applied. The SP8528

will also operate at a 3.3V supply at 45.15 µS

throughput. The device automatically shuts

down to a +0.5 µA (MAX) level as soon as the

chip is deselected (CS=1). Serial data output is

available in an MSB first or LSB first format.

FEATURES

2.5%

The input sampling scheme is full differential,

where the maximum full scale range is V . The

signal is applied between +IN and -I^RN^EF. The

signals applied at each input may both be

dynamic. This is in contrast with pseudo

differential devices which must have input low

held at a constant level during conversion. The

converter will provide significant common mode

rejection because of the full differential

sampling. Each input independently must

remain between ground and Vcc to avoid

clamping the inputs. For proper conversion the

differential input (+IN - -IN) must be less than

or equal to Vref.

The device can be configured such that it

delivers serial data MSB first requiring 15 clock

periods for a full conversion. Alternately, the

device can be programmed to deliver 12 bits of

data MSB first, followed by the same 12 bits of

data LSB first. This sequence will require 26

clock periods to complete. Please refer to the

timing diagram.

Circuit Operation

The SP8528 is a SAR converter with full

differential sampled front end, capacitive DAC,

precision comparator, SuccessiveApproximations

Register, control logic and data output register.

After the input is sampled and held the

conversion process begins. The DAC MSB is

set and its output is compared with the signal

input, if the DAC output is less than the input,

the comparator outputs a one which is latched

into the SAR and simultaneously made

available at the ADC serial output pin. Each bit

is tested in a similar manner until the SAR

contains a code which represents the signal input

to within +1/2 LSB. During this process the SAR

content has been shifted out of the ADC serially.

If the MSB first format was chosen, the data will

appear at the DOUT pin MSB through LSB in 15

clock periods. If LSB first data is desired, 26

SCLK’s are needed to

The device uses a capacitive DAC architecture

which provides the sampling behavior. This

results in full Nyquist performance at the

fastest throughput rate (33.2kHz) the device is

capable of.

The power supply voltage is variable from 3.0V

to 5.5V which provides supply flexibility.At the

5.0V supply level, conversion plus sampling

time is 30.1 µS and supply current is 230 µA

(1.15 mW). With a 3.3V supply the conversion

plus sampling time is 45.15 µS and current is

reduced to 80 µA (0.26 mW).

between conversions. The DOUT pin will be in a

high impedance state whenever Chip Select Bar

is high. After Chip Select Bar has been toggled

and brought low again, the converter begins a

new conversion.

A circuit board layout which includes separate

analog and digital ground planes will prevent

the coupling of noise into sensitive converter

circuits and will help to preserve the dynamic

performance of the device. In single ended

mode, the analog input signal should be

referenced to the ground pin of the converter.

This prevents any voltage drops that occur in

the power supply's common return from

appearing in series with the input signal.

Single Ended or Full

Differential Operation

The SP8528 has a balanced full differential front

end. The SP8528 can be used in this manner, or

it can be used in single-ended circuits as well.

For single-ended systems, simply tie the -IN to

the Reference Low of the input signal, which is

allowed to range from 0V to V . For a full

differential sampling configuratio^Cn^C, both inputs

are sampled and held simultaneously. Because

of the balanced differential sampling, dynamic

common mode noise riding along the input

signal is cancelled above and beyond DC noise.

This is a significant improvement over psuedo-

differential sampling schemes, where the low

side of the input must remain constant during

the conversion, and therefore only DC noise (i.e.

signal offset) is cancelled. IfAC common mode

noise is left to be converted along with the

differental component, the output signal will be

degraded.

In full differential mode, the high and low side

board traces should run close to each other, with

the same layout. This will insure that any noise

coupling will be common mode, and cancelled

by the converters (patent pending) full differential

architecture.

If separate analog and digital ground planes are

not possible, care should be used to prevent

coupling between analog and digital signals. If

analog and digital lines must cross, they should

do so at right angles. Parallel analog and digital

lines should be separated by a circuit board trace

which is connected to common.

The reference pin on the SP8528 should be kept

as clean as possible. A noise signal of 1.22mV

(for VREF = 5.0V) will produce 1 lsb of error

in the output code. For convenience, the VREF

pin can be tied to the VCC pin, but now the same

care should be taken with the VCC pin as with

the VREF pin. Whether or not VCC is tied to

VREF, the VCC pin should always be bypassed

to the GROUND pin with a parallel combination

of a 6.8µF tantalum and a 0.1µF ceramic

capacitor. To maintain maximum system

accuracy, the supply connected to the VCC pin

should be well isolated from digital supplies and

wide load variations.Aseparate conductor from

the supply regulator to the A/D converter will

limit the effects of digital switching elsewhere

in the system. Power supply noise can degrade

the converters performance. Especially corrupting

are noise and spikes from a switching power

supply.

Full differential sampling allows flexibility in

converting the input signal. If the signal low-

side is already tied to a ground elsewhere in the

system, it can be hardwired to the low side

input (i.e., -IN) which acts as a signal ground

sense, breaking a potential ground loop. It is also

possible to drive the inputs balanced differential,

as long as both inputs are within the power rails.

In this configuration, both the high and low

signals have the same impedance looking back

to ground, and therefore pick up the same noise

along the physical path from signal source (i.e.,

sensor, transducer, battery) to the converter. This

noise becomes common mode, and is cancelled

out by the differential sampling of the SP8528.

Layout Considerations

To preserve the high resolution and linearity of

the SP8528 attention must be given to circuit

board layout, ground impedance and bypassing.

To avoid introducing distortion when driving the

A/D converter input, the input signal source

should be able to charge the SP8528's equivalent

20 pF of input capacitance from zero volts to

the signal level in 1.5 clock periods.
