Texas Instruments ADS127L21EVM-PDK Evaluation Kit facilitates the evaluation of the ADS127L21. The ADS127L21 is a 24-bit, high-speed, custom-wide-bandwidth filter delta-sigma (ΔΣ) analog-to-digital converter (ADC). The ADS127L21EVM-PDK kit does not require an external power supply. The TI ADS127L21EVM-PDK Evaluation Kit includes an ADS127L21EVM board, a PHI controller board, and accompanying computer software that allows the user to communicate with the ADC over a universal serial bus (USB), capture data, and perform data analysis.
