TAS5630BDKDR

Overview

The TAS5630BDKDR is a Texas Instruments PurePath HD analog-input power stage. It delivers 300 W stereo or 400 W mono output into 2-ohm loads at 48 V. The device integrates Class-D and Class-G topologies with a fixed gain of 46 dB. Total harmonic distortion plus noise is specified at 0.03%. It operates on a supply voltage range from 25 V to 52.5 V. The component utilizes a 44-pin HSSOP package.

Feature Summary

• Integrates PurePath HD analog input architecture for high-fidelity audio processing
• Combines Class-D switching efficiency with Class-G rail management
• Includes integrated feedback loop circuitry

Applications

• High-power stereo audio amplification systems
• Mono channel audio power stages
• Professional audio equipment requiring analog input interfaces

Procurement Notes

Verify the specific suffix against manufacturer documentation, as packaging variations exist within the series. Confirm current availability status directly with authorized distributors, as lifecycle notifications may apply. Ensure thermal design aligns with the HSSOP-44 package requirements for the intended power output levels.

Selection Notes

Select this model when an analog input interface is required rather than digital. Compare against the TAS5631B if digital inputs are preferred. Verify that the 44-pin HSSOP footprint fits the target PCB layout. Ensure the application supports the 25 V to 52.5 V supply voltage range.

Part Context

This component belongs to the TAS5630B family of high-power audio amplifiers. It serves as the analog-input variant within the PurePath HD portfolio. The device is designed for applications demanding significant output power in a compact form factor compared to discrete solutions.

Replacement Considerations

TAS5630BDKD is a tube-packaged equivalent. TAS5630BPHDR offers a different HTQFP-64 package option.
