The ADS7816PC is a 12-bit sampling Analog-to-digital Converter (ADC) features low power operation with automatic power down, a synchronous serial interface and a differential input. The reference voltage can be varied from 100mV to VCC with a corresponding resolution from 24μV to 1.22mV. Low power, automatic power down and small size make the ADC ideal for battery operated systems or for systems where a large number of signals must be acquired simultaneously. It is also ideal for remote and/or isolated data acquisition.
