This user's guide describes the characteristics, operation, and use of the ADS8028EVM-PDK. This
evaluation module and performance development kit (EVM-PDK) is an evaluation system for the
ADS8028, a 12-bit, 1-MSPS, 8-channel, successive approximation register (SAR) analog-to-digital
converter (ADC). The EVM-PDK allows evaluation of all aspects of the ADS8028 device.
This document includes an EVM QuickStart section, hardware and software details, bill of materials, and
schematic.
