Operates From 10 V to 26 V  
DESCRIPTION  
Operates From +24 V LCD Backlight Supply  
The TPA3125D2 is a 10-W (per channel), efficient,  
class-D audio power amplifier for driving stereo  
speakers in a single-ended configuration; or, a mono  
Efficient Class-D Operation Eliminates Need  
for Heat Sinks  
Four Selectable, Fixed-Gain Settings  
Single-Ended Analog Inputs  
speaker in  
a bridge-tied-load configuration. The  
TPA3125D2 can drive stereo speakers as low as 4 .  
The efficiency of the TPA3125D2 eliminates the need  
for an external heat sink when playing music. 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  
20-Pin DIP Package  
Advanced Power-Off Pop Reduction  
The patented start-up and shutdown sequences  
minimize pop noise in the speakers without additional  
circuitry.  
The thru-hole package allows placement on  
single-sided printed circuit boards.
