Overview

The ADS127L21EVM-PDK is an evaluation platform for the ADS127L21 24-bit, high-speed custom-wide-bandwidth filter delta-sigma (ΔΣ) analog-to-digital converter (ADC). The evaluation kit includes the ADS127L21EVM board, the PHI controller board, and accompanying computer software that enables the user to communicate with the ADC over universal serial bus (USB), capture data, and perform data analysis.

Features
  • Includes hardware and software required for diagnostic testing, as well as accurate performance evaluation of the ADS127L21 ADC
  • No external power supply needed
  • Ships with PHI EVM controller, which provides convenient interface to the EVM over USB 2.0 (or higher) for power delivery and digital interface
  • Easy-to-use evaluation software for Windows 10, 64-bit operating systems; software suite includes graphical tool for data capture and analysis

  • Precision host interface board (PHI Board)
  • USB micro-B plug to USB-A plug cable
