  • Page 5: Overview

    Overview The ADS7056EVM-PDK is a platform for evaluating the performance of the ADS7056 SAR ADC, which is a single-ended analog input, 14-bit, 2.5-msps device. The evaluation kit includes the ADS7056EVM 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.
