The ADS931x is a high-speed, dual, simultaneous-sampling, analog-to-digital converter (ADC) with an integrated reference and reference buffer. The ADS931x has excellent AC performance, which makes the device optimum for wide-bandwidth data acquisition (DAQ) systems.

The device supports an SPI-compatible serial interface. This interface makes the ADS931x easy to pair with a diversity of microcontrollers, digital signal processors (DSPs), and field-programmable gate arrays (FPGAs). This device also supports a data averaging feature that provides an AC performance boost in noisy environments.
