DESCRIPTION
The ADS7817 is a 12-bit, 200kHz sampling analog-
to-digital converter (A/D) that features a high imped-
ance fully differential analog input. The reference
voltage can be varied from 100mV to 2.5V, with a
corresponding input-referred 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 SOIC-8, or an MSOP-8 package.
