TAS5631DKDR

Overview

The TAS5631DKDR is a stereo Class-D audio amplifier manufactured by Texas Instruments. It features PWM input and delivers 300W of output power. The device is part of the TAS563x family, designed for high-performance audio applications. It utilizes a universal input isolated PFC power supply reference design (SLOU293) for AVR amplifiers. The component is currently in an End-of-Life (EOL) status.

Feature Summary

• Stereo Class-D architecture with PWM input interface
• High-power output capability suitable for AV receivers
• Integrated thermal and protection mechanisms inherent to the TAS563x series

Applications

• Audio Video Receivers (AVR)
• Home theater systems
• High-fidelity stereo amplification

Procurement Notes

Verify current availability as the TAS5631DKDR is listed as an End-of-Life product. Check for discontinuance notifications or last-time-buy deadlines from Texas Instruments. Ensure compatibility with existing designs before sourcing remaining stock from authorized distributors.

Selection Notes

Consider the TAS5630 as a related alternative within the same family. Evaluate newer Class-D amplifiers from Texas Instruments if long-term supply stability is required. Review the SLOU293 reference design for power supply requirements associated with this amplifier class.

Part Context

The TAS5631DKDR belongs to the TAS563x series of digital-input Class-D audio amplifiers. These devices are engineered for high-efficiency, high-power audio applications. The DKDR suffix indicates the specific tape-and-reel packaging variant of the TAS5631 chip.

Replacement Considerations

No verified public substitute part numbers are available. The TAS5630 is a related family member but requires verification for direct pin-to-pin or functional equivalence.
