DESCRIPTION
•
•
Pin compatible with TAS5630, TAS5615 and
TAS5611
The TAS5613 is a high-performance analog input
Class
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.
D amplifier with integrated closed loop
Multiple Configurations Possible on the Same
PCB:

–
–
Mono Parallel Bridge Tied Load (PBTL)
Stereo Bridge Tied Load (BTL)
PurePath™ HD technology enables traditional
AB-Amplifier performance (<0.03% THD) levels while
providing the power efficiency of traditional class D
amplifiers.

Total Output Power at 10%THD+N
Unlike traditional Class-D amplifiers, the distortion
curve only increases once the output levels move into
clipping.

–
300W in Mono PBTL Configuration
150W per Channel in Stereo BTL
Configuration
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
