This user's guide describes the characteristics, operation and use of the ADS8350EVM performance

demonstration kit (PDK). This kit is an evaluation platform for the ADS8350, dual-channel, 16-bit,

simultaneous sampling, successive approximation register (SAR) analog-to-digital converter (ADC) that

supports pseudo-differential analog inputs. This EVM eases the evaluation of the ADS8350 device with

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

includes complete circuit descriptions, a schematic diagram, and a bill of materials.

Throughout this document, the terms demonstration kit, evaluation board, evaluation module are

synonymous with the ADS8350EVM-PDK.

Page 3: Overview
Overview The ADS8350EVM-PDK is a platform for evaluation of the ADS8350 analog-to-digital converter (ADC). The evaluation kit combines the ADS8350EVM board with a simple capture card controller board. The simple capture card controller board consists of a TI Sitara embedded microcontroller (AM3352) and a field programmable gate array (FPGA).

Page 8: Power Supplies
Power Supplies The analog portion of the ADS8350EVM-PDK requires a 5-V supply. The ADS8350EVM-PDK is configured at the factory using the onboard regulated analog 5-V supply (+VA); and an onboard 3.3-V digital supply. Alternatively, set the AVDD analog supply voltage by connecting an external power source through two-terminal connector J5.
