ADC1031/ADC1034/ADC1038 10-Bit Serial

I/O A/D Converters with Analog Multiplexer

and Track/Hold Function

General Description

Features

Serial I/O (MICROWIRE^TMcompatible)

The ADC1031, ADC1034 and ADC1038 are 10-bit succes-

sive approximation A/D converters with serial I/O. The seri-

al input, for the ADC1034 and ADC1038, controls a single-

ended analog multiplexer that selects one of 4 input chan-

nels (ADC1034) or one of 8 input channels (ADC1038). The

ADC1034 and ADC1038 serial output data can be config-

ured into a left- or right-justified format.

Separate asynchronous converter clock and serial data

I/O clock

Analog input track/hold function

Ratiometric or absolute voltage referencing

No zero or full scale adjustment required

0V to 5V analog input range with single 5V power

supply

An input track/hold is implemented by a capacitive refer-

ence ladder and sampled-data comparator. This allows the

analog input to vary during the A/D conversion cycle.

TTL/MOS input/output compatible

No missing codes

Separate serial I/O and conversion clock inputs are provid-

ed to facilitate the interface to various microprocessors.
