DESCRIPTION

The ADS7817 is a 12-bit, 200kHz sampling Analog-to-

Digital (A/D) converter that features a high impedance fully

differential analog input. 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.
