TAS5630DKDR

Overview

The TAS5630DKDR is a stereo Class-D audio amplifier manufactured by Texas Instruments. It delivers 300W of output power and accepts analog input signals. The device features integrated feedback loops to ensure signal integrity. It operates within a supply voltage range of 25V to 52.5V and supports load impedances of 2 Ohms and 4 Ohms. The unit achieves a total harmonic distortion plus noise (THD+N) of 0.03%. It is housed in an HTQFP-64 package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Stereo Class-D architecture with integrated feedback for high-fidelity audio reproduction
• Analog input interface for direct connection to standard audio sources
• High efficiency operation suitable for demanding power applications

Applications

• High-power home theater systems
• Professional audio amplification equipment
• Active loudspeaker designs requiring stereo output

Procurement Notes

Verify component authenticity through authorized channels as the part may be discontinued. Confirm package integrity and pin alignment prior to integration. Ensure design compatibility with the specified 25V to 52.5V supply requirements. Review thermal management needs for the HTQFP-64 package under full load conditions.

Selection Notes

Select this component for designs requiring high-output stereo power from analog inputs. Compare against digital input alternatives if system architecture permits. Evaluate thermal dissipation capabilities relative to the intended enclosure. Verify that the 300W rating aligns with the target speaker impedance and power supply constraints.

Part Context

This device belongs to the TAS5630 family of high-power audio amplifiers. It shares core specifications with variants such as the TAS5630BPHDR, differing primarily in package type. The series is designed for applications demanding significant audio output power with minimal external components.

Replacement Considerations

The TAS5630BPHDR serves as a verified alternative offering identical electrical performance in a different package format.
