TAS5614LADDV

Overview

The TAS5614LADDV is a PurePath HD digital input Class-D power stage from Texas Instruments, housed in a 44-pin HTSSOP package with an exposed thermal pad. It delivers 2x150W output in bridge-tied load stereo mode at 4 ohms and up to 300W in parallel bridge-tied mono mode at 2 ohms. The device integrates on-chip feedback for ultra-low distortion and high power supply rejection. Operating within a 12V to 38V supply range, it achieves over 90% efficiency and supports PWM digital audio inputs.

Feature Summary

• Integrates PurePath HD closed-loop feedback technology to minimize distortion and enhance power supply rejection ratio.

Applications

• Home theater systems
• AV receivers
• Soundbars
• Active subwoofers

Procurement Notes

Verify the specific suffix 'DDV' against the manufacturer's official datasheet to confirm the tube packaging configuration. Ensure compatibility with the required thermal management design for the HTSSOP-44 package. Confirm that the intended application utilizes a compatible external PWM modulator, as this component functions strictly as a power stage requiring digital input signals.

Selection Notes

Select this component when designing high-power audio systems requiring digital PWM inputs rather than analog signals. It is suitable for applications demanding high efficiency and low thermal dissipation due to its integrated feedback and advanced gate drive scheme. Ensure the system architecture can accommodate the necessary external components for the PurePath HD feedback loop and Class-G power control if utilized.

Part Context

This part belongs to the TAS5614LA series of high-performance digital input Class-D power stages. It is designed to work in conjunction with TI's digital front-end processors to create complete high-fidelity audio solutions. The series emphasizes high power density and audio quality through integrated feedback mechanisms.

Replacement Considerations

The TAS5614PHDR is listed as a discontinued alternative with different packaging. Verify pinout and thermal requirements carefully. No direct active substitute is confirmed in the provided data; consult the manufacturer for current equivalents.
