The ADS981x is an eight-channel data acquisition (DAQ) system 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, 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.
