The ADC10731, ADC10732 and ADC10734 are obsolete or on lifetime buy
and included for reference only.
This 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
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 is configured to comply with the MICROWIRE serial data exchange standard
for easy interface to the COPS and HPC families of controllers, and can easily interface with
standard shift registers and microprocessors.
