1 Overview

The ADS9218EVM-PDK is a platform for evaluating the performance of the ADS9218 SAR ADC, which is a fully differential input, 18-bit, 10-MSPS device. The evaluation kit includes the ADS9218EVM board and an FMC connecter adapter board used to interface the ADC with many FPGA kits. The TSWDC155EVM (sold separately) is a digital controller board that can be used with this evaluation kit and the EVM software GUI to communicate with the device, graph measured results, and compute common figures of merit (such as SNR and THD).
