1 Overview

The ADS9224REVM-PDK is an evaluation platform for the ADS9224R, a dual, simultaneous-sampling, 16-bit, 3-MSPS, fully-differential input successive approximation register (SAR) analog-to-digital converter (ADC). The ADS9224R features an enhanced serial multiSPI® digital interface. The evaluation kit includes the ADS9224REVM board and the Precision Host Interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC using a USB interface for data capture and analysis.

The ADS9224REVM board includes the ADS9224R SAR ADC, all the peripheral analog circuits, and components required to extract optimum performance from the ADC.

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 ADS9224R
  • Supplies power to all active circuitry on the ADS9224REVM-PDK board

Along with the ADS9224REVM and PHI controller board, this evaluation kit includes an A-to-micro-B USB cable to connect to a computer.
