Description

The TAS5631 is a high performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD) with the ability to drive up to 300W ⁽¹⁾ Stereo into 4 to 8 Speakers from a single 50V 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 only increases once the output levels move into clipping.

PurePath™ HD technology enables lower idle losses making the device even more efficient. Coupled with TI’s Class G power supply reference design for TAS563x, industry leading levels of efficiency can be achieved.
