3 Description

The ADS981x is an eight-channel data acquisition

(DAQ) system based on a dual, simultaneoussampling,

18-bit successive approximation register

(SAR) analog-to-digital converter (ADC). The

ADS981x features a complete analog front-end

for each channel with an input clamp, 1-MΩ

input impedance, independently programmable gain

amplifier (PGA), programmable low-pass filter, and an

ADC input driver. The device also features a low-drift,

precision reference with a buffer to drive the ADCs. A

high-speed digital interface supporting 1.2-V to 1.8-V

operation enables the ADS981x to be used with a

variety of host controllers.

The ADS981x can be configured to accept ±12-V,

±10-V, ±7-V, ±5-V, ±3.5-V, and ±2.5-V bipolar inputs.

The high input impedance allows direct connection

with sensors and transformers, thus eliminating the

need for external driver circuits. The high performance

and accuracy, along with zero-latency conversions

offered by this device make the ADS981x a great

choice for multiple industrial applications.
