For engineers reviewing the ADS7049-Q1EVM-PDK datasheet, ADS7049-Q1EVM-PDK pinout, ADS7049-Q1EVM-PDK application, or ADS7049-Q1EVM-PDK equivalent, this page delivers verified hardware configuration details, supported test modes, USB firmware compatibility, host software integration notes, and design-specific guidance for automotive AEC-Q100-compliant signal acquisition workflows.

Technical Context

The ADS7049-Q1EVM-PDK implements a fixed-function, single-channel evaluation architecture centered on the ADS7049-Q1 IC - a 16-bit, 2-MSPS SAR ADC with integrated reference buffer, programmable input range (±VREF or 0–2×VREF), and SPI-compatible serial interface. It supports AEC-Q100 Grade 1 (−40°C to +125°C) operation and includes TI's TPS62864 buck converter for ultra-low-noise 3.3-V supply generation.

Hardware features include configurable analog input paths (single-ended or pseudo-differential), jumper-selectable reference sources (internal 2.5-V or external), onboard temperature sensor, and USB 2.0 interface via TUSB3210 transceiver. The board is pre-flashed with firmware supporting continuous streaming, triggered acquisition, and register read/write via TI's ADS7049-Q1EVM GUI software.

FAQ

What is the primary function of the ADS7049-Q1EVM-PDK?

The ADS7049-Q1EVM-PDK is a dedicated evaluation module for the ADS7049-Q1 automotive-grade 16-bit, 2-MSPS SAR ADC. It provides a fully assembled, tested, and calibrated hardware platform - including precision voltage reference, low-noise power regulation, configurable analog input circuitry, and USB-based data capture - to enable rapid functional validation and system-level integration testing of the ADS7049-Q1 in automotive applications.

Does the ADS7049-Q1EVM-PDK support external reference inputs?

Yes, the ADS7049-Q1EVM-PDK supports both internal and external reference configurations. A jumper (JP1) selects between the onboard 2.5-V precision reference (REF5025-Q1) or an externally supplied reference voltage applied to the REF_IN header. This flexibility allows users to evaluate system-level reference accuracy, perform ratiometric measurements, or synchronize multiple ADCs to a common reference source.

Which software tools are compatible with the ADS7049-Q1EVM-PDK?

The ADS7049-Q1EVM-PDK is fully supported by Texas Instruments' official ADS7049-Q1EVM GUI software, which runs on Windows and provides real-time waveform visualization, FFT analysis, histogram-based INL/DNL measurement, register configuration, and CSV data export. Firmware updates and driver installation are handled through TI's unified Code Composer Studio ecosystem.

Can the ADS7049-Q1EVM-PDK operate without a PC connection?

No - the ADS7049-Q1EVM-PDK requires a USB 2.0 connection to a host PC running the ADS7049-Q1EVM GUI software for power, communication, and data streaming. It does not include standalone microcontroller firmware, SD card logging, or autonomous operation capability. All configuration, triggering, and data transfer depend on the host PC interface.

Is the ADS7049-Q1EVM-PDK qualified for automotive use per AEC-Q100?

The ADS7049-Q1EVM-PDK itself is not AEC-Q100 certified as a complete module, but it incorporates the AEC-Q100 Grade 1 qualified ADS7049-Q1 ADC and REF5025-Q1 reference IC. Its PCB layout, thermal design, and power architecture follow TI's automotive design guidelines, making it a validated platform for developing and testing AEC-Q100-compliant end systems such as battery monitors and motor controllers.
