Overview
The TAS5616DKDR is a high-performance Class-D audio amplifier from Texas Instruments, featuring PurePath HD digital input technology. It delivers 160 W of stereo output power or 300 W in mono configuration. The device operates within a supply voltage range of 18 V to 38 V and utilizes a 44-pin HSSOP package. Designed for low total harmonic distortion plus noise, it supports efficient digital audio processing with integrated thermal protection and short-circuit protection mechanisms.
Feature Summary
- PurePath HD digital input architecture for high-fidelity audio reproduction
- Configurable stereo (160 W) or mono (300 W) output power stages
- Integrated thermal and short-circuit protection for robust operation
Applications
- High-end home theater systems
- Professional audio amplification equipment
- Active loudspeaker designs requiring digital input interfaces
Procurement Notes
Verify the specific suffix DKDR against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compatibility with the intended digital audio interface protocols before integration. Check for any recent product lifecycle notices regarding availability or obsolescence status directly from Texas Instruments official channels.
Selection Notes
Select this component when high power density and digital input simplicity are required. It is suitable for designs needing significant output power without complex analog front-ends. Consider the thermal management requirements associated with 300 W mono operation and ensure the PCB layout supports the HSSOP-44 package thermal dissipation needs.
Part Context
This part belongs to the TAS56xx series of PurePath HD digital input power stages. It complements other TI audio solutions by offering a bridge between digital signal processing and high-power analog output. The series is designed to simplify system design by integrating necessary control logic and protection features into a single IC.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Texas Instruments application notes for potential cross-references within the TAS56xx family based on specific power and channel requirements.
