TAS5707APHPR

Overview

The TAS5707APHPR is a stereo digital audio power amplifier from Texas Instruments, housed in a 48-pin HTQFP package. It delivers 20 W of output power into an 8-ohm load with a supply voltage range of 8 V to 24 V. The device integrates I2S digital input, equalization (EQ), and dynamic range compression (DRC). It operates within a temperature range of 0°C to 85°C and requires a separate 3.3 V digital supply.

Feature Summary

• Integrates digital signal processing features including equalization and dynamic range compression for optimized audio performance.
• Supports direct digital interface via I2S input, eliminating the need for external DACs.
• Includes built-in protection mechanisms such as thermal shutdown and short-circuit protection.

Applications

• Portable multimedia devices requiring high-efficiency stereo amplification
• Digital audio systems utilizing I2S interfaces
• Consumer electronics needing integrated audio processing

Procurement Notes

Verify component authenticity through authorized distributors or TI directly. Confirm RoHS compliance and lead-free status. Check for moisture sensitivity level 3 handling requirements during storage and assembly. Ensure the 3.3 V digital supply rail is properly decoupled.

Selection Notes

Select this part for designs requiring integrated digital audio processing and stereo output. Verify compatibility with I2S source devices. Ensure the PCB layout supports the HTQFP-48 package thermal dissipation. Confirm that the application does not require analog inputs, as this model is digital-only.

Part Context

This component belongs to the TAS5707 family of digital audio amplifiers. It is designed for applications demanding high fidelity and efficiency. The device combines power stage capabilities with digital control features in a compact surface-mount package.

Replacement Considerations

TAS5805MPWPR is listed as a similar replacement option by distributors. Verify pinout and feature compatibility before substitution. Note that the TAS5707PHPR variant shares the same core functionality but may differ in packaging or lifecycle status.
