TAS5613APHD

Overview

The TAS5613APHD is a high-performance Class-D audio power amplifier from Texas Instruments, designed for stereo applications. It delivers up to 150W of output power and features PurePath HD technology for superior audio fidelity. The device operates with an analog input interface and utilizes a 64-pin HTQFP package with a PowerPad for thermal management. Key electrical specifications include a maximum supply voltage range of 18V to 38V and a total harmonic distortion plus noise (THD+N) of 0.05%. It supports a gain-bandwidth product of 80 kHz and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates PurePath HD technology to ensure high-fidelity audio reproduction with low distortion characteristics.
• Features a robust thermal design utilizing a PowerPad in the HTQFP-64 package for efficient heat dissipation during high-power operation.
• Supports analog input signals with integrated protection mechanisms against short circuits and thermal overload.

Applications

• High-end home theater systems requiring high-power stereo amplification
• Professional audio equipment demanding low distortion and high dynamic range
• Premium consumer electronics such as soundbars and AV receivers

Procurement Notes

Verify the specific suffix 'PHD' to confirm the tray packaging and commercial grade temperature rating. Ensure compatibility with the required 18V to 38V supply rails. Confirm that the 64-pin HTQFP footprint matches the target PCB layout. Check for moisture sensitivity level requirements during assembly processing.

Selection Notes

Select this component when a stereo configuration with analog inputs is required. It is suitable for designs needing up to 150W per channel with strict THD+N limits. Consider the HTQFP-64 package constraints for thermal performance. Compare against TAS5613 variants if different packaging or extended temperature ranges are needed.

Part Context

This part belongs to the TAS5613A series of high-power audio amplifiers. It is distinct from the standard TAS5613 due to its specific packaging and grade. The series is known for integrating digital control interfaces alongside analog inputs in some variants, though this specific model focuses on analog input functionality within the PurePath HD ecosystem.

Replacement Considerations

TAS5613APHDR is a reel-packaged alternative with identical electrical specifications. TAS5613PHD offers similar performance but may differ in packaging type and operational temperature range. Verify pinout and thermal pad connections before substitution.
