ADC08831/ADC08832

8-Bit Serial I/O CMOS A/D Converters with Multiplexer

and Sample/Hold Function

General Description

The ADC08831/ADC08832 are 8-bit successive approxima-

tion Analog to Digital converters with 3-wire serial interfaces

and a configurable input multiplexer for 2 channels. The se-

rial I/O will interface to COPS™family of micro-controllers,

PLD’s, microprocessors, DSP’s, or shift registers. The serial

I/O is configured to comply with the NSC MICROWIRE™ se-

rial data exchange standard.

To

minimize

total

power

consumption,

the

ADC08831/ADC08832 automatically go into low power

mode whenever they are not performing conversions.

A track/hold function allows the analog voltage at the positive

input to vary during the actual A/D conversion.

The analog inputs can be configured to operate in various

combinations

of

single-ended,

differential,

or

pseudo-differential modes. The voltage reference input can

be adjusted to allow encoding of small analog voltage spans

to the full 8-bits of resolution.

Applications

n Digitizing sensors and waveforms

n Process control monitoring

n Remote sensing in noisy environments

n Instrumentation

n Embedded Systems

Features

n 3-wire serial digital data link requires few I/O pins

n Analog input track/hold function

n 2-channel input multiplexer option with address logic

n Analog input voltage range from GND to VCC

n No zero or full scale adjustment required

n TTL/CMOS input/output compatible

n Superior pin compatible replacement for ADC0831/2
