TAS5631BPHDR Description

Short technical summary and product information.

The Texas Instruments TAS5631BPHDR is a high-performance Class-D audio amplifier designed for demanding audio applications. It delivers up to 300W in stereo mode or 400W in mono PBTL configuration, powered by a supply voltage ranging from 25V to 52.5V.

 

This amplifier boasts an ultralow Total Harmonic Distortion plus Noise (THD+N) of 0.03% at 1 kHz into a 4Ω load, ensuring high-fidelity sound reproduction. It supports a signal bandwidth of up to 80 kHz, capturing high-frequency content from HD sources. The device features PurePath HD technology and integrated feedback for enhanced audio quality, including 80-dB PSRR and over 100-dB SNR.

 

Available in HSSOP (DKD) and HTQFP (PHD) packages, the TAS5631BPHDR is suitable for surface mounting. It includes self-protection features such as undervoltage, overtemperature, clipping, and short-circuit protection with error reporting. Applications include mini combo systems, AV receivers, DVD receivers, and active speakers.
