Description
ADS7953SDBTR is TI’s Starter Development Board (SDB) for evaluating the ADS7953, a 12‑bit SAR ADC. It provides a quick, hands‑on platform to test the ADC’s performance and SPI interface with a host controller. Typical features include the ADS7953 device with an on‑board reference, multiple analog inputs (single‑ended or differential), a SPI‑compatible serial interface, and power options (USB or external supply, commonly 3.3 V/5 V). The board includes input connectors, jumpers, and headers to simplify signal routing, plus example code and documentation to help you measure DC accuracy, linearity, noise, and sampling behavior and to integrate the ADC into a larger system. It’s suitable for evaluation, prototyping, and educational use with microcontrollers, DSPs, or FPGAs via SPI. For exact specifications, pinout, and software, refer to the ADS7953SDBTR data sheet and TI product page.
