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.
