TAS5631BPHD Description

Short technical summary and product information.

The Texas Instruments TAS5631BPHD is a high-performance Class-D audio amplifier designed for demanding audio applications. It provides up to 300W in stereo mode or 400W in mono PBTL configuration, operating from a power stage supply voltage range of 25V to 52.5V.

This amplifier features a PWM input and utilizes TI's PurePath HD technology for superior audio fidelity, including a signal bandwidth up to 80 kHz and ultralow total harmonic distortion plus noise (THD+N) of 0.03% at 1W into 4Ω. It supports multiple configurations such as Stereo BTL, Mono PBTL, and Quad Single-Ended outputs, offering design flexibility.

The TAS5631BPHD is available in thermally enhanced HSSOP (DKD) and HTQFP (PHD) packages. It includes integrated self-protection features for undervoltage, overtemperature, clipping, and short-circuit protection, ensuring reliable operation. The amplifier is suitable for applications like home audio systems, AV receivers, DVD receivers, and active speakers.

With an efficiency greater than 88% and low output MOSFET on-resistance, this Class-D amplifier minimizes power consumption and heat generation. Its operating temperature range is from 0°C to 70°C, making it suitable for a wide array of consumer electronics.
