Overview
The TAS2563RPPR, produced by Texas Instruments, is a digital input Class-D audio amplifier designed to efficiently drive high peak power into small loudspeakers. This amplifier is optimized for applications requiring high audio quality and robust speaker protection. It features an integrated 11.5V Class-H boost, enabling it to deliver up to 6.1W of peak power into a 4Ω load at a battery voltage of 3.6V, or up to 10W peak power using an external 12V supply in boost bypass mode. The TAS2563 also includes an on-chip, low-latency DSP that supports Texas Instruments' SmartAmp speaker protection algorithms, ensuring real-time monitoring and protection of the loudspeakers.
