This user's guide describes the characteristics, operation and use of the ADS8354EVM and

ADS7854EVM performance demonstration kits (PDKs). These kits are evaluation platforms for the

ADS8354 and ADS7854, dual-channel, 16-bit and 14-bit, simultaneous sampling, successive

approximation register (SAR) analog-to-digital converters (ADCs) that support fully-differential analog

inputs. These EVMs ease the evaluation of the ADS8354 and ADS7854 devices with hardware and

software for computer connectivity through a universal serial bus (USB). This user's guide includes

complete circuit descriptions, schematic diagrams, and bills of material.

Throughout this document, the terms ADSxx54EVM-PDK, demonstration kit, evaluation board, evaluation

module are synonymous with the ADS8354EVM-PDK and ADS7854EVM-PDK.
