The reference voltage can be varied from 100mV to 2.5V, with a corresponding inputreferred resolution between 49µV and 1.22mV. The differential input, low power, automatic power down, and small size make the ADS7817 ideal for direct connection to transducers in battery operated systems, remote data acquisition, or multi-channel applications. The ADS7817 is available in a plastic mini-DIP-8, an SO-8, or an MSOP-8 package.
