• Integrated feedback for low distortion
• High efficiency power stage design

Applications

• Home theater systems
• AV receivers
• Soundbars

Procurement Notes

Verify the specific suffix 'DKDR' against current manufacturer documentation to confirm availability status. Check for official End-of-Life notifications or Product Change Notices that may affect long-term supply stability. Ensure compatibility with existing thermal management designs specified in the datasheet.

Selection Notes

Select this component when a digital PWM interface is required for high-power audio applications. It is suitable for designs needing integrated feedback to minimize external components. Consider the HSSOP-44 package constraints for PCB layout and thermal dissipation requirements in the target enclosure.

Part Context

This part belongs to the TAS5614A series of high-performance audio amplifiers. It is designed as a complete power stage solution, integrating the driver and MOSFETs. The series targets consumer audio markets requiring high fidelity and efficient power delivery from digital sources.

Replacement Considerations

TAS5614LADDVR offers similar performance with an HTSSOP-44 package and extended temperature range.
