DESCRIPTION
The TAS5611A 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 125W
(1)
Stereo into 4 to 8
Speakers from a single 32.5V 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 Power PAD™
PurePath™ HD technology enables lower idle losses
making the device even more efficient.

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.
