Overview
The TAS5612LADDV is a high-performance Class-D audio power stage manufactured by Texas Instruments. It delivers 125 W of continuous stereo output power and 250 W of mono output power into 4-ohm loads. The device features PurePath HD digital input technology, supporting high-definition audio formats with low total harmonic distortion plus noise (THD+N) of 0.03%. It operates from a single supply voltage ranging from 12 V to 38 V. The component is housed in a 44-pin HTSSOP package with an exposed pad for thermal management.
Feature Summary
- Integrates PurePath HD digital input interface for direct connection to digital audio sources without external DACs
- Provides high-efficiency Class-D amplification suitable for demanding audio applications
- Supports flexible configuration for both stereo and mono bridge-tied load operations
Applications
- Home theater systems
- Professional audio equipment
- High-fidelity speaker systems
Procurement Notes
Verify the specific suffix 'ADDV' corresponds to the tube packaging format when ordering. Confirm that the design supports the required thermal dissipation for the HTSSOP-44 package under maximum load conditions. Ensure the digital audio interface timing matches the source device specifications to maintain signal integrity.
Selection Notes
Select this component for designs requiring high power density and digital input integration. Compare against the TAS5614LADDV if higher power output is needed. Consider the TAS5612APHD if a different package type or analog input capability is preferred. Evaluate thermal constraints carefully due to the high power ratings.
Part Context
This part belongs to the TAS5612LA series of digital-input Class-D power stages. It is designed to replace older analog amplifier solutions in high-power audio systems. The series includes variants like the TAS5614LADDV for increased power handling. It represents Texas Instruments' focus on integrating digital processing with power amplification.
Replacement Considerations
The TAS5612LADDVR is the reel-packaged equivalent of this tube-packed component. The TAS5614LADDV offers higher power output but requires similar layout considerations. Verify pin compatibility before substituting with other Class-D amplifiers.
