The TAS2781 and TAS2783 are digital input Class-D smart audio amplifiers with speaker protection. The TAS2783 additionally supports the MIPI Alliance SoundWire interface with SoundWire Device Class Audio (SDCA). An on-chip low-latency digital-signal processor (DSP) supports advanced audio enhancement and speaker protection algorithms. The advanced audio enhancement algorithms improve audio quality, increase clarity, reduce noise, and provide rich bass, and dynamic playback. This document describes the various audio enhancement algorithms that are in the TAS2781 and TAS2783 amplifiers.
