ADS8354EVM-PDK Evaluation Module
This user's guide describes the characteristics, operation, and use of the ADS8354 evaluation module (EVM)
performance demonstration kit (PDK). This kit is an evaluation platform for the ADS8354 device, which is a 16-
bit, dual-channel, simultaneous-sampling, 700-kSPS, differential analog input, successive approximation register
(SAR) analog-to-digital converter (ADC) that features an easy-to-use serial programming interface (SPI). The
ADS8354EVM-PDK eases evaluation with hardware, software, and computer connectivity through the universal
serial bus (USB) interface. This user's guide includes complete circuit descriptions, schematic diagrams, and a
bill of materials (BOM). Throughout this document, the terms evaluation board, evaluation module, and EVM are
synonymous with the ADS8354EVM-PDK.
