Description

The ADS8681WEVM-PDK is a platform for evaluating the performance of the ADS8681W, an integrated data acquisition system based on a successive approximation register (SAR) analog-to-digital converter (ADC). This device features a high-speed, high-precision SAR ADC, integrated differential analog front-end (AFE) input driver circuit, over-voltage protection circuit up to ±20V, and an on-chip 4.096V reference with extremely low temperature drift. The evaluation kit includes the ADS8681WEVM board and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over Universal Serial Bus (USB) for data capture, configuration, and analysis.
