ADS981x 8-Channel Data Acquisition (DAQ) System

Texas Instruments ADS981x 8-Channel Data Acquisition (DAQ) System is based on a dual, simultaneous-sampling, 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 protection circuit. It also has a programmable gain amplifier (PGA) and 1MΩ input impedance with user-selectable bandwidth options. The high input impedance allows direct connection with transformers and sensors, thus eliminating the need for external driver circuits. The ADS981x can accept unipolar or bipolar inputs up to a ±12V common-mode voltage.
