1 ADS8688EVM-PDK Evaluation Module

GUID-20200901-CA0I-QGMS-RSL8-SNGHS8NWTX6K-low.gifADS8688EVM-PDK

This user's guide describes the operation and use of the ADS8688 evaluation module (EVM). The ADS8688 is a 16-bit, 500ksps, 8 channel multiplexed, single-supply, SAR ADC with bipolar input ranges. Operating on a single 5V the integrated analog front end can support ±10.24V input ranges with a ±20V over-voltage protection. The performance demonstration kit (PDK) eases EVM evaluation with additional hardware and software for computer connectivity through a universal serial bus (USB). The ADS8688EVM-PDK includes the ADS8688EVM as a daughter card, Precision Host Adaptor (PHI) digital controller, and a A-to-B USB cable. This user's guide covers circuit description, schematic diagram, and bill of materials for the ADS8688EVM daughter card.
