TAS5711PHPR

Overview

The TAS5711PHPR is a high-efficiency, digital-input Class-D audio power amplifier manufactured by Texas Instruments. It features a 48-pin HTQFP package and supports stereo bridge-tied speaker loads. The device operates on an 8V to 26V supply voltage range and delivers up to 20W of output power into an 8-ohm load. It accepts I2S serial digital audio inputs with sampling rates from 8kHz to 48kHz. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of less than 0.1% and a power conversion efficiency exceeding 90%. The component functions within a temperature range of 0°C to 85°C.

Feature Summary

• Integrates a fully programmable data path for routing discrete audio channels directly to internal speaker drivers without external DACs.
• Includes comprehensive protection mechanisms such as over-current, thermal shutdown, DC offset, and under-voltage lockout.
• Supports seamless integration with digital audio processors and MPEG decoders via a single serial data input interface.

Applications

• Television systems
• iPod dock stations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and compliance status. Confirm that the requested part number matches the exact pinout and functional requirements for the target design. Check for any recent product change notifications regarding assembly sites or material composition updates before finalizing procurement orders.

Selection Notes

Select this component for designs requiring direct digital audio interfacing to minimize bill-of-materials complexity. Ensure the system power supply can maintain stability within the 8V to 26V operating range during peak load conditions. Verify that the PCB layout accommodates the thermal requirements of the HTQFP-48 package to sustain high-efficiency operation.
