DESCRIPTION  
Flat THD at all Frequencies for Natural  
Sound  
The TAS5630 is a high-performance analog-input  
class-D amplifier with integrated closed-loop  
feedback technology (known as PurePath HD  
technology) with the ability to drive up to 300 W  
stereo into 4-to 8-speakers from a single 50-V  
80-dB PSRR (BTL, No Input Signal)  
>100-dB (A-weighted) SNR  
(1)  
Click- and Pop-Free Start-Up  
supply.  
Multiple Configurations Possible on the Same  
PCB With Stuffing Options:  
PurePath HD technology enables traditional  
AB-amplifier performance (<0.03% THD) levels while  
providing the power efficiency of traditional class-D  
amplifiers.  
Mono Parallel Bridge-Tied Load (PBTL)  
Stereo Bridge-Tied Load (BTL)  
2.1 Single-Ended Stereo Pair and  
Bridge-Tied Load Subwoofer  
Unlike traditional class-D amplifiers, the distortion  
curve only increases once the output levels move into  
clipping. PurePath HD™  
Quad Single-Ended Outputs  
Total Output Power at 10% THD+N  
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 exposed package heat  
slug and the heat sink should be used to achieve high output  
power levels.
