12-Bit Differential Input Micro Power Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● BIPOLAR INPUT RANGE

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.

● TRUE DIFFERENTIAL INPUT

● 200kHz SAMPLING RATE

● MICRO POWER: 2.3mW at 200kHz

● POWER DOWN: 3µA Max

● AVAILABLE IN MSOP-8 PACKAGE

● SERIAL INTERFACE

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.
