Page 4: Overview
Overview The ADS9110EVM-PDK is a platform for evaluating the performance of the ADS9110 SAR ADC, which is a fully-differential input, 18-bit, 2-MSPS device. The evaluation kit includes the ADS9110EVM board and the Precision Host Interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over USB for data capture and analysis.
