DESCRIPTION
The TAS5630B 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⁾
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™
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.

(1) Achievable output power levels are dependent on the thermal
configuration of the target application. A high-performance
thermal interface material between the exposed package heat
slug and the heat sink should be used to achieve high output
power levels.
