The TAS5631B is a high-performance PWM input class-D amplifier with integrated closed-loop feedback technology (known as PurePath HD technology) with the ability to drive up to 300 W ⁽¹⁾ stereo into 4-Ω to 8-Ω speakers from a single 50-V supply.

PurePath HD technology enables traditional AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D amplifiers.

Unlike traditional class-D amplifiers, the distortion curve does not increase until the output levels move into clipping.

PurePath HD technology enables lower idle losses, making the device even more efficient.
