TAS2560 Class-D Mono Audio Amplifier

Texas Instruments TAS2560 Class-D Mono Audio Amplifier is a low-power, high-performance, digital input, boosted amplifier that can easily be implemented in mono and stereo (x2) applications. The device features an ultra-low-noise audio DAC and Class-D power amplifier. The Texas Instruments TAS2560 features incorporate speaker voltage and current sensing feedback with speaker protection algorithms. A Class-H boost converter generates the Class-D amplifier supply rail. When the audio signal requires only a lower Class-D output power, system efficiency is improved by deactivating the boost and connecting VBAT directly to the Class-D amplifier supply. When a higher audio output power is required, the multi-level boost re-activates, tracking the signal to provide the additional voltage to the load.
