The integrated DSP of the TAS5827 enables Class-H envelope tracking, eliminating the need for development of complex tracking software or an external microcontroller
Onboard LM5155 boost to evaluate Class-H efficiency performance and provide customer system design reference
Default system configuration: 5 V battery input, boost to max 20 V power rail based on audio envelope tracking
Optional hardware control mode to set switching frequency, analog gain, BTL/PBTL mode and Cycle by Cycle current limit through pin configuration
Provides flexible input signal routing (USB, analog, optical and external I2S)
Demonstration, evaluation and development environment via the PurePath Console 3 software (GUI)
