DESCRIPTION
The TAS5630 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 Ω
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 Premier Pro™Power PAD™
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 package exposed
heatslug and the heat sink should be used to achieve high
output power levels.
