DESCRIPTION The ADS7816 is a 12-bit, 200kHz sampling analog-to-digital converter. It features low power operationwith automatic power down, a synchronous serialinterface, and a differential input. The reference volt-age can be varied from 100mV to 5V, with a corre-sponding resolution from 24µV to 1.22mV.Low power, automatic power down, and small sizemake the ADS7816 ideal for battery operated systemsor for systems where a large number of signals must beacquired simultaneously. It is also ideal for remoteand/or isolated data acquisition.
