ADC
Figure above shows the ADC0834-N 4-Channel MUX SOIC/PDIP
The figure above shows the ADC0834-N which is of the ADC0831 series, and is 8-bit successive approximation A/D converters with a serial I/O and configurable input multiplexer with up to 8 channels. The serial I/O is configured to comply with the TI MCROWIRE serial data exchange standard for easy interface to COPS family of processors, and can interface with standard shift registers or µPs.
