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.
