The ADS9803 is an
eight-channel data acquisition (DAQ) system based on a simultaneous sampling, 20-bit
successive approximation register (SAR) analog-to-digital converter (ADC). The ADS9803 features a complete analog front-end (AFE) for
each channel with an input clamp. The device also features a 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. Configure the ADS9803 to accept ±12V, ±10V, ±7V, ±5V, ±3.5V, and
±2.5V bipolar inputs with up to ±12V input common-mode voltage.
A digital interface supporting 1.2V to 1.8V operation enables the ADS9803 to be used without external voltage level translators.
