TAS5711PHP

Overview

The TAS5711PHP is a high-performance, high-efficiency digital input Class-D audio power amplifier manufactured by Texas Instruments. Designed for stereo bridge-tied speaker applications, it integrates a professional audio DSP processing unit and stereo power output modules within a single chip. The device natively supports I2S digital audio input, eliminating the need for external DACs. It operates on an 8V to 26V supply voltage range and delivers up to 20W of rated output power into an 8-ohm load at 24V with 10% THD. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of ≤0.1%, a power conversion efficiency of ≥90%, and a supply current of 55 mA. The component utilizes a 48-pin HTQFP package.

Feature Summary

• Integrates a programmable data path and internal speaker drivers for seamless connection to digital audio processors without external DACs.
• Includes built-in audio processing capabilities such as independent channel volume control, dynamic range control, and multiple programmable biquad filters for equalization.
• Features comprehensive protection mechanisms including thermal shutdown, short-circuit protection, and DC offset protection to ensure operational stability.

Applications

• Stereo bridge-tied speaker systems in consumer electronics
• Digital audio amplification in television sets
• Soundbar audio processing units
• Portable media docks requiring efficient digital audio playback

Procurement Notes

Verify the specific suffix against official datasheets, as variations may indicate different packaging or environmental compliance standards. Confirm the active status and lead times directly with authorized distributors or the manufacturer. Ensure compatibility with the target PCB footprint, specifically the 48-pin HTQFP package dimensions. Validate that the supply voltage range aligns with the system design requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring direct digital audio inputs to reduce bill of materials complexity. It is suitable for applications prioritizing high efficiency and low heat generation due to its Class-D architecture. Consider the integrated DSP features if external audio processing hardware needs to be minimized. Ensure the application environment stays within the specified operating temperature range of 0°C to 85°C.
