Texas Instruments ADS9224REVM-PDK

Overview

ADS9224REVM-PDK from Texas Instruments is an evaluation module and performance demonstration kit for the ADS9224R dual-channel, 16-bit, 3-MSPS SAR ADC. It integrates the ADS9224R IC, THS4551 fully-differential input drivers, TPS7A4700 low-noise LDO, REF5025 voltage reference, and a Precision Host Interface (PHI) controller board. The kit enables USB-powered evaluation of high-precision data acquisition in test, metrology, and industrial sensing applications.

For engineers reviewing the ADS9224REVM-PDK datasheet, ADS9224REVM-PDK setup, ADS9224REVM-PDK GUI software, or ADS9224REVM-PDK jumper configuration, this page provides verified hardware architecture, power delivery topology, digital interface modes (multiSPI™/SPI), analog signal path design, and supported analysis tools - all specific to the ADS9224REVM-PDK evaluation platform.

Technical Context

The ADS9224REVM-PDK implements a complete signal chain: SMA and header-based analog inputs feed into two THS4551 FDAs configured for 1-kΩ input impedance and 1.5-MHz bandwidth, driving the ADS9224R's dynamic SAR inputs at full 3-MSPS throughput. The PHI controller provides USB 2.0 host connectivity, 5.5-V-to-5-V regulation via TPS7A4700, and 3.3-V digital supply directly from its LDO.

Digital communication uses multiSPI™ or standard SPI over dedicated SDO/SDI/SCLK/CS/CONVST lines, with configurable SDO width (1/2/4 lanes) and data rate (SDR/DDR). Onboard EEPROM stores initialization data, while REF/2 (2.048 V) sets common-mode voltage for differential input stages, and LM7705 supplies –230 mV to VS– for rail-to-rail amplifier output swing.

FAQ

What is the ADS9224REVM-PDK used for?

The ADS9224REVM-PDK is an evaluation module for the ADS9224R 16-bit, 3-MSPS dual SAR ADC. It provides hardware, firmware, and Windows GUI software to perform real-time data capture, spectral analysis, histogram testing, and linearity evaluation - enabling rapid prototyping and performance validation of precision data acquisition systems before full-system integration.

Does the ADS9224REVM-PDK require an external power supply?

No. The ADS9224REVM-PDK is USB-powered via the included A-to-micro-B cable and the PHI controller board. The PHI derives 5.5 V from USB, regulates it to clean 5 V for analog circuitry using the TPS7A4700, and supplies 3.3 V to the digital section - eliminating need for external bench supplies during standard evaluation.

Which ADC does the ADS9224REVM-PDK support?

The ADS9224REVM-PDK is purpose-built for the ADS9224R - a dual, simultaneous-sampling, 16-bit, 3-MSPS SAR ADC with fully-differential inputs and enhanced multiSPI™ digital interface. It does not support other ADC variants (e.g., ADS9226, ADS9234) without hardware or firmware modification.

How is analog signal interfacing implemented on the ADS9224REVM-PDK?

The ADS9224REVM-PDK provides four SMA connectors (J2–J5) and four header jumpers (JP1–JP4) for analog input. Each channel uses a THS4551 FDA with 1-kΩ input impedance and 1.5-MHz bandwidth. JP1 and JP4 can be shunted to ground negative inputs for single-ended operation, while REF/2 (2.048 V) sets common-mode level and LM7705 supplies –230 mV to VS– for full-scale swing.

What software is included with the ADS9224REVM-PDK?

The ADS9224REVM-PDK includes a Windows GUI application built on LabVIEW Runtime Engine. It supports time-domain waveform viewing, FFT-based spectral analysis, histogram generation, INL/DNL linearity assessment, and reference settling analysis - with data export to CSV/text for post-processing. Installation requires disabling antivirus temporarily and accepting unsigned driver prompts.
