ADS9224REVM-PDK
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.
1.1 ADS9224REVM-PDK Features
The ADS9224REVM-PDK includes the following features:
• Hardware and software required for diagnostic testing as well as accurate performance evaluation of
the ADS9224R ADC
• USB powered—no external power supply is required
• A PHI controller that provides a convenient communication interface to the ADS9224R ADC over USB
2.0 (or higher) for power delivery as well as digital input and output
• Easy-to-use evaluation software for Windows
®
7, 8, and 10, 64-bit operating systems
• The software suite includes graphical tools for data capture, histogram analysis, spectral analysis,
linearity analysis, and reference settling analysis. This suite also has a provision for exporting data to a
text file for post-processing.
1.2 ADS9224REVM Features
The ADS9224REVM includes the following features:
• Onboard low-noise and low distortion ADC fully-differential amplifier input drivers optimized to meet
ADC performance
• Onboard ultra-low-noise, low-dropout (LDO) regulator for excellent, 5-V single-supply regulation of the
voltage reference and all the fully-differential amplifier input drivers
