3 Description

The ADS981x is an 8-channel data acquisition (DAQ)

system based on a dual, simultaneous-sampling, 18-

bit successive approximation register (SAR) analogto-

digital converter (ADC). The ADS981x features a

complete analog front-end for each channel with an

input clamp protection circuit, 1MΩ input impedance,

and a programmable gain amplifier (PGA) with

user-selectable bandwidth options. The high input

impedance allows direct connection with sensors and

transformers, thus eliminating the need for external

driver circuits. The ADS981x can be configured to

accept unipolar or bipolar inputs with up to a ±12V

common-mode voltage.

The device also features a 4.096V reference for the

ADC and a 2.5V reference output for use with external

circuits. A digital interface supporting 1.2V to 1.8V

operation enables the ADS981x to be used without

external voltage level translators.
