FEATURES  
DESCRIPTION  
The LM4952 is a dual audio power amplifier primarily  
designed for demanding applications in flat panel  
monitors and TV's. It is capable of delivering 3.1  
watts per channel to a 4Ω single-ended load with less  
than 1% THD+N when powered by a 12VDC power  
supply.

Low Current, Active-low Shutdown Mode  
Low Quiescent Current  
Stereo 3.8W Output, RL = 4Ω  
DC-controlled Volume Control  
Short Circuit Protection  
Eliminating external feedback resistors, an internal,  
DC-controlled, volume control allows easy and  
variable gain adjustment.  
APPLICATIONS  
Boomer audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. The  
LM4952 does not require bootstrap capacitors or  
snubber circuits. Therefore, it is ideally suited for  
display applications requiring high power and minimal  
size.

KEY SPECIFICATIONS  
The LM4952 features a low-power consumption  
active-low shutdown mode. Additionally, the LM4952  
features an internal thermal shutdown protection  
mechanism along with short circuit protection.

The LM4952 contains advanced pop & click circuitry  
that eliminates noises which would otherwise occur  
during turn-on and turn-off transitions.
