1 EVM Overview

The evaluation kit includes the ADS131B26Q1EVM-PDK board and the precision host interface (PHI) controller board. The PHI board enables the accompanying computer software to communicate with the ADC over the universal serial bus (USB) for data capture and analysis.

The PHI board primarily serves three functions:

  • Provides a communication interface between the EVM and the computer through a USB port
  • Provides the digital input and output signals necessary to communicate with the ADS131B26Q1EVM-PDK
  • Supplies power to all active circuitry on the ADS131B26Q1EVM-PDK board
