1.1 Introduction

The ADS131E08EVM-PDK is a platform for evaluating the performance of the ADS131E08, a 24-bit, 64-kSPS, 8-channel, simultaneous-sampling delta-sigma ADC. The evaluation kit includes the ADS131E08 EVM and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over USB for data capture and analysis. The ADS131E08 EVM includes the ADS131E08 and all the peripheral analog circuits and components required to evaluate the performance of the ADS131E08. The PHI controller primarily serves three functions:

  • Provides a communication interface from the ADS131E08 EVM to the computer through a USB port
  • Provides the digital input and output signals necessary to communicate with the ADS131E08 ADC
  • Supplies power to all active circuitry on the ADS131E08 EVM

This user's guide includes complete circuit descriptions, schematic diagrams, and a bill of materials. Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the ADS131E08 EVM.
