Texas Instruments ADS1147EVM-PDK

Overview

ADS1147EVM-PDK from Texas Instruments is a complete evaluation kit for the ADS1147 16-bit delta-sigma analog-to-digital converter, comprising the ADS1147EVM board, MMB3 motherboard, USB interface, and ADCPro™ software. It supports ±2.5V or +5V analog supply, onboard 2.048V reference, GPIO access, and SPI/I²C digital interfaces for full functional validation in precision sensor signal chains.

For engineers reviewing the ADS1147EVM-PDK datasheet, ADS1147EVM-PDK pinout, ADS1147EVM-PDK application, or ADS1147EVM-PDK equivalent, this kit delivers out-of-box evaluation of resolution, noise, INL/DNL, gain/offset calibration, and multiplexed thermocouple/resistance temperature detector (RTD) measurement performance without custom firmware or hardware design.

Technical Context

The ADS1147EVM-PDK integrates the ADS1147EVM daughter card with the MSP430F449-based MMB3 motherboard to provide a self-contained USB-powered evaluation platform. The MMB3 supplies regulated ±5V, +3.3V, and +1.8V rails and implements virtual COM port communication via TUSB3410.

ADCPro software controls all ADS1147 registers-including data rate (up to 2kSPS), PGA gain (1–128), reference selection (internal 2.048V or external), multiplexer configuration, and calibration modes-via a plug-in architecture supporting real-time scope, FFT, and histogram analysis.

FAQ

What is the ADS1147EVM-PDK and what does it include?

The ADS1147EVM-PDK is a complete evaluation kit from Texas Instruments that includes the ADS1147EVM daughter board, MMB3 motherboard, USB cable, and ADCPro™ software. It enables full functional evaluation of the ADS1147 16-bit delta-sigma ADC-including register configuration, noise analysis, and calibration-without requiring custom hardware or firmware. The ADS1147EVM-PDK supports both unipolar (+5V) and bipolar (±2.5V) analog supply modes and integrates an onboard 2.048V reference.

Does the ADS1147EVM-PDK require external power supplies?

No-the ADS1147EVM-PDK is fully USB-powered via the MMB3 motherboard, which generates all required rails: ±5V analog, +3.3V and +1.8V digital, and ±10V auxiliary outputs. This eliminates dependency on external bench supplies during initial evaluation. The ADS1147EVM-PDK draws power exclusively from the host PC's USB port and requires no additional AC/DC adapters or lab power sources for standard operation.

Which software is used with the ADS1147EVM-PDK and what features does it offer?

The ADS1147EVM-PDK uses ADCPro™ software with the dedicated ADS1147EVM-PDK plug-in. This Windows-based tool provides real-time register-level control of the ADS1147-including data rate, PGA gain, reference selection, and multiplexer routing-as well as built-in analysis functions: oscilloscope view, FFT spectrum, histogram, and statistical metrics (ENOB, SINAD, THD). All ADS1147EVM-PDK settings update instantly on hardware without recompilation or reset.

Can the ADS1147EVM-PDK evaluate both ADS1147 and ADS1247 devices?

Yes-the ADS1147EVM-PDK hardware is mechanically and electrically identical for both the ADS1147 (16-bit) and ADS1247 (24-bit) devices. The same PCB, MMB3 interface, and ADCPro plug-in support either IC. The ADS1147EVM-PDK user guide explicitly states that "operation of the EVM and kit for the ADS1147 is identical" to the ADS1247EVM-PDK unless otherwise noted, and the plug-in auto-detects device type via ID register reads.

What are the supported operating systems for the ADS1147EVM-PDK software?

The ADS1147EVM-PDK software officially supports Microsoft Windows XP only. Windows Vista and later versions-including Windows 7, 10, and 11-are not supported per the SBAU148B User's Guide (May 2011 revision). The ADCPro installer and Virtual COM port driver (TUSB3410) rely on legacy Windows XP kernel interfaces and will not function reliably on modern OS versions without compatibility layers or virtualization.
