ADC0831/ADC0832/ADC0834/ADC0838 8-Bit Serial I/O A/D Converters with Multiplexer Options
July 2002
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
serial data exchange
standard for easy interface to the COPS
family of proces-
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.
