DESCRIPTION
2-, 4- or 8-Channel Multiplexer Options with
Address Logic
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 TI
MICROWIRE serial data exchange standard for easy
interface to the COPS family of processors, and can
interface with standard shift registers or μPs.

Remote Operation with Serial Digital Data Link
TTL/MOS Input/Output Compatible
The 2-, 4- or 8-channel multiplexers are software
configured for single-ended or differential inputs as
well as channel assignment.
0.3 in. Standard Width, 8-, 14- or 20-Pin PDIP
Package
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.
