open-in-new Find other Speaker amps


The TAS5828M is a stereo high-performance closed-loop Class-D with integrated audio processor with up to 192-kHz architecture.

While setting into Hardware control mode, TAS5828M supports switching frequency, analog gain, BTL/PBTL mode and Cycle by Cycle current limit threshold through pin configuration. This mode is especially designed to elminate end system software driver integration efforts.
