TAS5631BPHDR

Overview

The TAS5631BPHDR is a digital-input power stage from Texas Instruments, part of the PurePath HD family. It delivers 300 watts of stereo output power or 400 watts in mono configuration. The device utilizes a digital input interface and integrates advanced closed-loop architecture to ensure high-fidelity audio reproduction with ultra-low distortion. Designed for high-efficiency operation, it eliminates the need for large heatsinks or transformers, thereby reducing bill of materials and total solution cost in professional and consumer audio applications.

Feature Summary

• Integrates PurePath HD technology for high-definition media playback
• Features greater than 88 percent efficiency
• Supports digital input interfaces

Applications

• Professional audio systems
• Home theater-in-a-box units
• Mini/micro component systems

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout compatibility and thermal specifications. Ensure the design supports the required digital input protocols. Confirm that the target application environment matches the specified operating temperature range. Cross-reference the package type with PCB layout guidelines provided in the official documentation.

Selection Notes

Select this component when designing systems requiring high-power stereo or mono audio amplification with digital inputs. It is suitable for applications where space constraints prohibit large passive components due to its high efficiency. Consider the PurePath HD integration for systems demanding low distortion and high dynamic range without external processing overhead.

Part Context

This device belongs to the TAS563x series of Class-D audio amplifiers. It shares architectural similarities with the TAS5630 but differs in input type, offering digital connectivity instead of analog. The series is positioned for high-performance audio solutions, competing in the segment of powerful home theater and professional sound reinforcement equipment.

Replacement Considerations

Public confirmed substitute part numbers include TAS5631BPHDG4 and TAS5631BPHD.A.
