1 EVM Overview

The evaluation kit includes the ADS1285EVM-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 because the ADS1285EVM-PDK does not contains a microprocessor on the board.

The PHI board primarily serves three functions:

  • Provides a communication interface from the EVM to the computer through a USB port
  • Provides the digital input and output signals necessary to communicate with the ADS1285EVM-PDK
  • Supplies power to all active circuitry on the ADS1285EVM-PDK board
