Description for the TAS5827
The TAS5827 is a stereo high-performance, closed-loop Class-D with integrated audio processor and up to 192-kHz audio support.
When setting the device into Hardware control mode, TAS5827 supports selecting switching frequency, analog gain, BTL/PBTL mode and cycle by cycle current limit threshold through pin configuration. This mode is designed to eliminate end system software driver integration efforts.
