ADC10731

This ADC10731 series of CMOS 10-bit plus sign successive approximation A/D converters features versatile analog input multiplexers, sample/hold and a 2.5V band-gap reference. The 1-, 2-, 4-, or 8-channel multiplexers can be software configured for single-ended or differential mode of operation.

An input sample/hold is implemented by a capacitive reference ladder and sampled-data comparator. This allows the analog input to vary during the A/D conversion cycle.

In the differential mode, valid outputs are obtained even when the negative inputs are greater than the positive because of the 10-bit plus sign output data format.

The serial I/O ADC10731 is configured to comply with the NSC MICROWIRE™ serial data exchange standard for easy interface to the COPS^TM and HPC^TM families of controllers, and can easily interface with standard shift registers and microprocessors.
