The DRV5825PEVM evaluation module (EVM) showcases the latest TI digital input Class-D closed-loop amplifier for Piezo application. The DRV5825P is a digital input Class-D audio amplifier with Smart Piezo Driver Algorithm. The EVM can be used as stand-alone platform with default I2C register settings. The EVM also works with PPC3 GUI for programming I2C register settings.

  • Smart Piezo driver algorithm for Piezo applications
  • Runs with I2C initialization
  • GUI control via USB port
