ADC0831/ADC0832/ADC0834/ADC0838

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

General Description

The ADC0831 series are 8-bit successive approximation A/D

converters with a serial I/O and configurable input multiplex-

ers with up to 8 channels. The serial I/O is configured to

comply with the NSC MICROWIRE

standard for easy interface to the COPS

sors, and can interface with standard shift registers or µPs.

The 2-, 4- or 8-channel multiplexers are software configured

for single-ended or differential inputs as well as channel

assignment.

The differential analog voltage input allows increasing the

common-mode rejection and offsetting the analog zero input

voltage value. In addition, the voltage reference input can be

adjusted to allow encoding any smaller analog voltage span

to the full 8 bits of resolution.
