The TAS2563 is a digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeakers. The Class-D amplifier is capable of delivering 6.1W of peak power into a 4Ω load at battery voltage of 3.6V using the integrated 11.5V Class-H boost, or 10W peak power into 4Ω load in boost bypass mode using external 12V supply.

An on-chip, low-latency DSP supports Texas Instruments SmartAmp speaker protection algorithms. The integrated current and voltage sense provides for real-time monitoring of the loudspeakers, which permits pushing peak sound pressure levels (SPL) while keeping speakers from being damaged.

The integrated look-ahead Class-H boost dynamically adjusts boost voltage during playback, increasing efficiency and saving battery life in battery-powered systems. For regulated wall-powered systems, TAS2563 also features a boost bypass mode, supporting supply voltages of up to 16V for even higher output power.

Two PDM microphone inputs simplify the audio signal chain for two-way audio systems, interfacing digital microphones with the host processor. A battery-tracking peak voltage limiter with brown-out protection prevents systems shutdowns by optimizing amplifier headroom over the entire charge cycle.
