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 TI
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.
