10-W/ch into an 4-Load From a 17-V Supply  
15-W/ch into an 8-Load From a 28-V Supply  
Operates from 10 V to 30 V  
DESCRIPTION  
The TPA3122D2 is a 15-W (per channel) efficient,  
Class-D audio power amplifier for driving stereo  
single ended speakers or mono bridge tied load. The  
TPA3122D2 can drive stereo speakers as low as 4.  
The efficiency of the TPA3122D2 eliminates the need  
for an external heat sink when playing music.  
Efficient Class-D Operation  
Four Selectable, Fixed Gain Settings  
Internal Oscillator (No External Components  
Required)  
Single Ended Analog Inputs  
The gain of the amplifier is controlled by two gain  
select pins. The gain selections are 20, 26, 32, and  
36 dB.  
Thermal and Short-Circuit Protection with  
Auto Recovery Feature
