General Description

The ADC0831 series are 8-bit successive approximation A/D converters with a serial I/O and configurable input multiplexers with up to 8 channels. The serial I/O is configured to comply with the NSC MICROWIRE™ serial data exchange standard for easy interface to the COPS™ family of processors, 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.

Features

NSC MICROWIRE compatible-direct interface to COPS family processors
Easy interface to all microprocessors, or operates "stand-alone"

Operates ratiometrically or with 5 V_DC voltage reference
No zero or full-scale adjust required
2-, 4- or 8-channel multiplexer options with address logic
Shunt regulator allows operation with high voltage supplies
0V to 5V input range with single 5V power supply
Remote operation with serial digital data link
TTL/MOS input/output compatible
0.3" standard width, 8-, 14- or 20-pin DIP package
20 Pin Molded Chip Carrier Package (ADC0838 only)
Surface-Mount Package

Key Specification

Resolution	8 Bits
Total Unadjusted Error	±½ LSB and ±1 LSB
Single Supply	5 V_DC
Low Power	15 mW
Conversion Time	32 µs
