TAS5709APHP

Overview

The TAS5709APHP is a Class-D stereo audio amplifier manufactured by Texas Instruments, housed in an HTQFP-48 surface-mount package. It delivers 20.6 W of output power into an 8 Ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a supply voltage ranging from 8 V to 24 V and supports I2S digital audio input. It functions within a temperature range of 0°C to +85°C.

Feature Summary

• Stereo Class-D architecture for high-efficiency audio amplification
• Integrated I2S digital interface for direct connection to digital sources
• Low distortion performance ensuring high-fidelity sound reproduction

Applications

• Portable multimedia speakers
• Home theater systems
• Digital audio players

Procurement Notes

Verify the specific suffix 'P' indicates tray packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure the HTQFP-48 footprint matches the design layout. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component for applications requiring stereo output with digital I2S connectivity. Consider the 8V to 24V supply range for compatibility with system power rails. Evaluate thermal management needs given the 20W output capability in the specified package.

Part Context

This part belongs to the TAS5709A series of audio amplifiers. It shares the same core functionality as the TAS5709APHPR variant, differing primarily in the shipping package configuration. Both variants utilize the same HTQFP-48 leaded plastic quad flatpack outline.

Replacement Considerations

TAS5709APHPR serves as a functional substitute with identical electrical characteristics, differing only in reel versus tray packaging.
