ADC0833 8-Bit Serial I O A D Converter
with 4-Channel Multiplexer
General Description
The ADC0833 series is an 8-bit successive approximation
A D converter with a serial I O and configurable input multi-
plexer with 4 channels The serial I O is configured to com-
ply with the NSC MICROWIRE^TM serial data exchange stan-
dard for easy interface to the COPS^TM family of processors
as well as with standard shift registers or mPs
The 4-channel multiplexer is software configured for single-
ended or differential inputs when channel assigned by a 4-
bit serial word
The differential analog voltage input allows increasing the
common-mode rejection and offsetting the analog zero in-
put voltage value In addition the voltage reference input
can be adjusted to allow encoding any smaller analog volt-
age span to the full 8 bits of resolution
