DESCRIPTION  
•
•
•
Operates From 10 V to 26 V  
The TPA3121D2 is a 15-W (per channel), efficient,  
class-D audio power amplifier for driving stereo  
speakers in a single-ended configuration or a mono  
Can Run From +24 V LCD Backlight Supply  
Efficient Class-D Operation Eliminates Need  
for Heat Sinks  
speaker in  
a bridge-tied-load configuration. The  
TPA3121D2 can drive stereo speakers as low as 4 Ω.  
The efficiency of the TPA3121D2 eliminates the need  
for an external heat sink when playing music.  
•
•
Four Selectable, Fixed-Gain Settings  
Internal Oscillator to Set Class D Frequency  
(No External Components Required)  
The gain of the amplifier is controlled by two gain  
select pins. The gain selections are 20, 26, 32, and  
36 dB.  
•
•
Single-Ended Analog Inputs  
Thermal and Short-Circuit Protection With  
Auto Recovery  
The patented start-up and shutdown sequences  
minimize pop noise in the speakers without additional  
circuitry.
