Texas Instruments ADC124S101EVM

Overview

ADC124S101EVM from Texas Instruments is a BoosterPack-style evaluation module designed to accelerate development with the ADC124S101 4-channel, 12-bit, 50–200 kSPS serial-output analog-to-digital converter in VSSOP-10 packaging. It integrates the ADC124S101CIMM/NOPB, LM4120IM5-3.3 voltage reference, LMT84DCK temperature sensor, and LMV612MA dual op-amp on a compact board that interfaces directly with MSP430 LaunchPad development platforms.

For engineers reviewing the ADC124S101EVM datasheet, ADC124S101EVM pinout, ADC124S101EVM application, or ADC124S101EVM equivalent, this module enables rapid validation of signal chain performance-including channel multiplexing, reference stability, temperature-sensing accuracy, and SPI interface timing-across industrial sensing, data acquisition, and embedded monitoring use cases.

Technical Context

The ADC124S101EVM implements a complete signal conditioning and digitization path: U2 (ADC124S101CIMM) provides 4 single-ended input channels with programmable sample rate up to 200 kSPS and SPI-compatible serial output; U1 (LM4120IM5-3.3) delivers a stable 3.3-V reference with ±0.5% initial accuracy and 75 ppm/°C drift; U3 (LMT84DCK) supplies calibrated analog temperature output on Channel 3 with ±1.5°C accuracy from –55°C to 150°C.

Board-level design supports direct connection to MSP430 LaunchPad via JA/JB/JC/JD headers, uses 0603 passives for layout compactness, and includes dedicated test points (GND, VA-EXT) for probing analog and digital signals during characterization. Firmware and GUI software enable real-time waveform capture, burst-mode sampling (1024 conversions), and CSV export of continuous read data.

FAQ

What is the primary function of the ADC124S101EVM?

The ADC124S101EVM is an evaluation module built around the ADC124S101CIMM/NOPB 4-channel, 12-bit SAR ADC. Its primary function is to provide a ready-to-use hardware and software platform for validating signal chain performance-including channel switching, reference stability, temperature sensing, and SPI communication-with MSP430 LaunchPad controllers. The ADC124S101EVM simplifies early-stage design verification without custom PCB development.

Which microcontroller platforms is the ADC124S101EVM compatible with?

The ADC124S101EVM is specifically designed for plug-and-play compatibility with Texas Instruments MSP430 LaunchPad development kits using the standard JA/JB/JC/JD 10-pin headers. It relies on MSP430 firmware (v0.92) and the ADC12xS10x GUI software for operation. While not officially validated for other platforms, its SPI interface and 3.3-V logic levels may permit adaptation to compatible ARM or RISC-V boards with appropriate level-shifting and driver support.

Does the ADC124S101EVM include on-board temperature sensing capability?

Yes-the ADC124S101EVM integrates the LMT84DCK analog temperature sensor (U3) connected to Channel 3 of the ADC124S101CIMM. This enables direct Celsius readout in the ADC12xS10x GUI when selecting "Temperature" output type. The LMT84DCK provides factory-trimmed accuracy of ±1.5°C across –55°C to 150°C, allowing immediate thermal characterization without external sensors or calibration.

What software is required to operate the ADC124S101EVM?

Operation requires the ADC12xS10x GUI software (v1.1), which supports Windows OS and communicates with the ADC124S101EVM via USB through the MSP430 LaunchPad. The software enables channel selection (0–3), output format (decimal code, mV, or °C), single/continuous/burst sampling modes, real-time waveform display, and CSV data export. Firmware upgrade (adc12xs10x_fw-v0.92.txt) and TI CDC USB drivers are also mandatory prerequisites.

Can the ADC124S101EVM be used for production systems?

No-the ADC124S101EVM is an evaluation module intended solely for research, development, and feasibility testing per TI's Standard Terms and Conditions for Evaluation Modules. It is not qualified for production use, lacks long-term supply guarantees, and contains components (e.g., unshielded layout, non-industrial-grade passives) unsuitable for end-equipment deployment. For production, designers must implement the ADC124S101CIMM/NOPB on a custom PCB meeting system-level EMI, reliability, and regulatory requirements.
