TAS5613APHDR

Overview

The TAS5613APHDR is a high-performance Class-D audio power amplifier from Texas Instruments' PurePath HD series. It delivers up to 150W of stereo output power or 300W in mono configuration. The device operates on a supply voltage range of 18V to 38V and features analog inputs with differential signal support. Key electrical specifications include a gain-bandwidth product of 80 kHz, total harmonic distortion plus noise of 0.05%, and a quiescent current of 20 mA. It is housed in a 64-pin HTQFP package with exposed pad for thermal management.

Feature Summary

• Integrates PurePath HD technology for high-fidelity audio reproduction with low distortion characteristics.
• Supports flexible mono and stereo operating modes via configurable internal architecture.
• Includes built-in protection mechanisms such as short-circuit and thermal shutdown capabilities.

Applications

• High-power home theater systems
• Professional audio amplification equipment
• Active loudspeaker designs requiring efficient power delivery

Procurement Notes

Verify the specific suffix 'APHDR' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure that the ordering quantity aligns with the standard reel packaging requirements specified by Texas Instruments. Confirm moisture sensitivity level handling procedures are followed upon receipt to prevent damage during assembly.

Selection Notes

Select this component when designing systems requiring high output power efficiency with analog input interfaces. Consider the 64-HTQFP package constraints for PCB layout and thermal dissipation strategies. Evaluate the 18V to 38V supply voltage range against the system's power budget and battery constraints if applicable.

Part Context

This part belongs to the TAS5613A family of digital audio amplifiers designed for demanding audio applications. It serves as a solution for bridging the gap between high-quality analog sources and efficient Class-D power stages. The device is intended for use in environments where audio fidelity and power density are critical design parameters.

Replacement Considerations

The TAS5613ADKDR is a documented alternative within the same family, though it utilizes a different 44-HSSOP package. Verify pin-to-pin compatibility and thermal performance differences before substitution. Other variants may exist but require careful evaluation of package and electrical parameter alignment.
