The TAS5630 is a high-performance analog-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⁾ Achievable output power levels are dependent on the thermal configuration of the target application.

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.
