Texas Instruments ADS1247EVM-PDK

Overview

ADS1247EVM-PDK from Texas Instruments is a complete evaluation kit for the ADS1247 24-bit delta-sigma analog-to-digital converter (ADC), comprising the ADS1247EVM daughter board, MMB3 motherboard, USB interface, and ADCPro™ evaluation software. It supports ±2.5V or +5V analog supply, onboard 2.048V buffered reference, and full SPI/I²C digital control for precision sensor signal acquisition in industrial and instrumentation applications.

For engineers reviewing the ADS1247EVM-PDK datasheet, ADS1247EVM-PDK pinout, ADS1247EVM-PDK application, or ADS1247EVM-PDK equivalent, this kit delivers turnkey evaluation of ADS1247 performance-including multiplexed differential inputs, programmable gain, internal/external reference selection, and GPIO-controlled biasing-without custom firmware or hardware design.

Technical Context

The ADS1247EVM-PDK integrates the ADS1247EVM evaluation module with the MSP430F449-based MMB3 motherboard to provide a self-contained USB-connected ADC test platform. It uses the ADS1247's internal oscillator by default and routes all digital signals-including CS, SCLK, DIN, DOUT/DRDY, START, MR, and PWRSEL-through J7 header pins with 3.3V CMOS logic levels (I²C pins compliant with 3.3V I²C rules).

Analog interface is provided via dual 10-pin Samtec headers (J4/J8) supporting up to four differential input channels (AIN0–AIN3), with RC filtering and optional external reference injection at REF+ and REF−. Power is fully supplied over USB, with MMB3 generating ±5V analog, +3.3V digital, and +1.8V digital rails required by the ADS1247.

FAQ

What is the ADS1247EVM-PDK and what does it include?

The ADS1247EVM-PDK is a complete evaluation kit from Texas Instruments that includes the ADS1247EVM daughter board, MMB3 motherboard, USB cable, and ADCPro™ evaluation software. It enables full functional and performance testing of the ADS1247 24-bit delta-sigma ADC without requiring additional hardware or custom firmware. The ADS1247EVM-PDK supports both SPI and I²C communication, onboard voltage reference, and configurable analog input routing.

Does the ADS1247EVM-PDK require external power supplies?

No-the ADS1247EVM-PDK is fully powered via USB through the MMB3 motherboard, which internally generates ±5V analog, +3.3V digital, and +1.8V digital supplies required by the ADS1247. No external power supplies are needed for standard operation, though optional external references or analog sources may be connected via J4/J8 headers.

Which software is used with the ADS1247EVM-PDK and what operating systems does it support?

The ADS1247EVM-PDK uses ADCPro™ software, a Windows-based evaluation tool developed by Texas Instruments. It officially supports only Microsoft Windows XP; Windows Vista and later versions are not supported. The software provides real-time data visualization (scope, FFT, histogram), register-level configuration, calibration tools, and GPIO control-all accessible through the ADS1247EVM-PDK plug-in.

How is firmware loaded onto the MMB3 when using the ADS1247EVM-PDK?

Firmware is loaded automatically by the ADS1247EVM-PDK plug-in within ADCPro™ during first use. When connection fails, the software prompts to download firmware to the MMB3's MSP430F449 microcontroller. The user must switch SW4 on the MMB3 to BSL mode (left position), then confirm in the dialog box. Firmware is stored in flash memory and requires only one-time loading unless updated manually.

Can the ADS1247EVM-PDK evaluate both the ADS1247 and ADS1147 devices?

Yes-the ADS1247EVM-PDK is functionally identical for evaluating both the ADS1247 (24-bit) and ADS1147 (16-bit) devices. The same hardware, firmware, and ADCPro™ plug-in support both parts, as they share pin compatibility, register maps, and interface protocols. Differences in resolution and noise performance are reflected in software measurements but require no hardware changes.
