Product details
Overview
ADC161S626EVM from Texas Instruments is an evaluation module designed to characterize the ADC161S626 - a 16-bit, 50 kSPS to 250 kSPS SAR analog-to-digital converter with differential inputs, internal sample-and-hold, and 4.096 V reference support. It integrates the ADC161S626CIMM (VSSOP-10) and LMP8350MA (SOIC-8) precision driver amplifier for high-fidelity signal conditioning in precision data acquisition systems.
For engineers reviewing the ADC161S626EVM datasheet, ADC161S626EVM pinout, ADC161S626EVM application, or ADC161S626EVM equivalent, this EVM enables rapid validation of dynamic performance (SNR, THD), SPI interface timing, reference stability, and differential input drive requirements using the included GUI software and MSP430 LaunchPad interface.
Technical Context
The ADC161S626EVM implements a complete signal chain: the LMP8350 fully differential amplifier conditions single-ended or differential inputs before feeding the ADC161S626's true differential input stage. The board supports both on-board 4.096 V reference (LM4120AIM5-4.1) and external VREF via test point VREF-EXT.
Communication uses a 3-wire SPI interface (SCLK, DOUT, CS) between the ADC161S626 and MSP430 LaunchPad, with firmware preloaded for 50 kHz sampling. Power is supplied via LaunchPad's 5 V (VA) and 3.3 V (VIO) rails, and jumper-configurable headers (J2, JVREF) allow flexible signal routing and reference selection.

FAQ
What is the primary function of the ADC161S626EVM?
The ADC161S626EVM is an evaluation module that enables hardware and software validation of the ADC161S626 - a 16-bit, 50–250 kSPS SAR ADC. It provides a complete, tested signal chain including the LMP8350 driver amplifier, on-board 4.096 V reference, SPI interface to MSP430 LaunchPad, and GUI-based data capture. The ADC161S626EVM allows engineers to verify real-world performance metrics such as SNR, THD, and INL before system integration.
Does the ADC161S626EVM require external power supplies?
No - the ADC161S626EVM draws all operating power from the connected MSP430 LaunchPad via its 5 V (VA) and 3.3 V (VIO) pins. No external bench supplies or regulators are needed. The board includes dedicated decoupling capacitors (0.1 µF and 10 µF) for each rail, and the LM4120AIM5-4.1 reference IC is powered from the 5 V rail, ensuring stable reference voltage without auxiliary sources.
How is the ADC161S626EVM connected to a host PC?
The ADC161S626EVM connects to a host PC through the MSP430 LaunchPad's USB interface. The LaunchPad acts as a bridge: it receives commands via USB CDC virtual COM port, executes SPI transactions with the ADC161S626, and streams digitized samples back to the PC. The included ADC1x1S62x GUI software communicates over this COM port and requires the MSP430_CDC_PID0x094e_ADC_DAC_EVMs.inf driver.
Can the ADC161S626EVM operate with an external reference voltage?
Yes - the ADC161S626EVM supports external VREF via the VREF-EXT test point. When pins 1–2 of the JVREF header are shorted, the ADC161S626's VREF pin is disconnected from the on-board LM4120AIM5-4.1 and routed to VREF-EXT. This allows users to evaluate performance with custom references (e.g., higher-precision or temperature-compensated sources) while maintaining full compatibility with the GUI and firmware.
What software tools are provided for the ADC161S626EVM?
Texas Instruments provides the ADC1x1S62x GUI software, which runs on Windows and supports real-time waveform plotting, single-shot reads, burst-mode capture, and configurable output formats (mV or decimal). Firmware (adc161s626_fw-v0.95-50kHz-PID0x094e) is preloaded on shipped units, and the GUI installer includes drivers, documentation (SNOU130A), and schematic/BOM files. No third-party IDE or compiler is required for basic operation.
