The ADC0833 series is an 8-bit successive approximation A D converter with a serial I O and configurable input multiplexer with 4 channels The serial I O is configured to comply with the NSC MICROWIRETM serial data exchange standard for easy interface to the COPSTM family of processors as well as with standard shift registers or mPs The 4-channel multiplexer is software configured for singleended or differential inputs when channel assigned by a 4bit serial word 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
