TAS2563RPPR

Overview

The TAS2563RPPR is a digital input Class-D audio amplifier optimized for driving high peak power into small loudspeakers. It features an integrated 11.5V, 12-step Look-Ahead Class-H boost and delivers 6.1W output at 1% THD+N into a 4Ω load with a 3.6V battery supply. The device includes a low-latency DSP supporting SmartAmp speaker protection algorithms, real-time I/V-sense monitoring, and two PDM microphone inputs. It operates on a VBAT range of 2.5V to 5.5V and utilizes a 32-pin QFN package.

Feature Summary

• Integrated 11.5V, 12-step Look-Ahead Class-H boost dynamically adjusts voltage during playback to increase efficiency.
• On-chip low-latency DSP supports Texas Instruments SmartAmp speaker protection algorithms including thermal and over-excursion limits.
• Real-time current and voltage sense provides continuous monitoring of the loudspeaker to prevent damage while maximizing sound pressure levels.
• Two PDM microphone inputs simplify the audio signal chain for two-way audio systems by interfacing directly with the host processor.

Applications

• Smart phones, tablets, and laptops
• Smart speakers with voice assistance
• Bluetooth and wireless speakers
• IP cameras

Procurement Notes

Verify the specific RPPR suffix against the manufacturer's datasheet to confirm the 32-pin QFN package configuration. Ensure that the design accommodates the required VBAT and VDD supply voltages as specified in the recommended operating conditions. Confirm compatibility with the intended I2S/TDM or I2C control interfaces before finalizing procurement.

Selection Notes

Select this component when designing battery-powered portable devices requiring high peak power from small loudspeakers. The integrated Class-H boost eliminates the need for external boost circuitry in many applications. Consider the internal DSP capabilities if advanced speaker protection or audio processing features are required without additional host processor overhead.
