1.1 Introduction

The ADS125R14EVM-PDK is a platform for evaluating the performance of the ADS125R14, a 24-bit, 8-channel, 320-kSPS multiplexed delta-sigma ADC designed for low-latency, high-precision data acquisition systems. The evaluation kit includes the ADS125R14 EVM board and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over the USB for data capture and analysis. The ADS125R14 EVM includes the ADS125R14 and all the peripheral analog circuits and components required to evaluate the performance of the ADS125R14. The PHI board provides a communication interface from the ADS125R14 EVM to the computer through a USB port.

This EVM 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 ADS125R14EVM.
