3 Description
The ADS9813 is an eight-channel data acquisition
(DAQ) system based on a simultaneous sampling, 18-
bit successive approximation register (SAR) analogto-
digital converter (ADC). The ADS9813 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 ADS9813
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 ADS9813 to be used without external
voltage level translators.
