FEATURES  
DESCRIPTION  
23  
Active Enabled Integrated Feedback Provides:  
(PurePath™ HD Technology)  
The TAS5615 is a high-performance analog input  
class-D amplifier with integrated closed-loop  
feedback technology (known as PurePath™ HD  
technology). It has the ability to drive up to 160  
W(1) stereo into 8-speakers from a single 50-V  
supply.  
Signal Bandwidth up to 80 kHz for  
High-Frequency Content From  
High-Definition Sources  
Ultralow 0.03% THD at 1 W into 8  
0.03% THD Across All Frequencies for  
Natural Sound at 1 W  
PurePath HD technology enables traditional  
AB-amplifier performance (<0.03% THD) levels while  
providing the power efficiency of traditional class-D  
amplifiers.  
80-dB PSRR (BTL, No Input Signal)  
>100-dB (A weighted) SNR  
Click- and Pop-Free Start-Up  
Ultralow 0.03% THD+N is flat across all frequencies,  
ensuring that the amplifier does not add uneven  
distortion characteristics, and helps maintain a natural  
sound.  
Minimal External Components Compared to  
Discrete Solutions  
Multiple Configurations Possible on the Same  
PCB:  
The efficiency of this class-D amplifier is greater than  
90%. Undervoltage protection, overtemperature,  
clipping, short-circuit and overcurrent protection are  
all integrated, safeguarding the device and speakers  
against fault conditions that could damage the  
system.  
Mono Parallel Bridge-Tied Load (PBTL)  
2.1 Single-Ended (SE) Stereo Pair and  
Bridge-Tied Load (BTL) Subwoofer  
Quad Single-Ended (SE) Outputs  
Total Output Power at 10% THD+N

(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
