DESCRIPTION
The TAS5613A is a high-performance analog input
Class D amplifier with integrated closed loop
feedback technology (known as PurePath™ HD). It
has the ability to drive up to 150 W.⁽¹⁾ Stereo into 4Ω
speakers from a single 36V 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.

(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
