This user's guide describes the characteristics, operation, and use of the ADS7953 evaluation module (EVM) performance demonstration kit (PDK). This kit is an evaluation platform for the ADS7953 device, which is a 12-bit, 16-channel, 1-MSPS, single-ended analog input, successive approximation register (SAR) analog-to-digital converter (ADC) that features an easy-to-use serial programming interface (SPI). The ADS7953EVM-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 ADS7953EVM-PDK.
