LM4952  
3.1W Stereo-SE Audio Power Amplifier  
with DC Volume Control  
General Description  
Key Specifications  
The LM4952 is a dual audio power amplifier primarily de-  
signed for demanding applications in flat panel monitors and  
TV’s. It is capable of delivering 3.1 watts per channel to a 4  
single-ended load with less than 1% THD+N when powered  
by a 12VDC power supply.

Eliminating external feedback resistors, an internal, DC-  
controlled, volume control allows easy and variable gain  
adjustment.  
Features  
n Pop & click circuitry eliminates noise during turn-on and  
turn-off transitions  
n Low current, active-low shutdown mode  
n Low quiescent current  
n Stereo 3.8W output, RL = 4Ω  
n DC-controlled volume control  
n Short circuit protection  
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 boot-  
strap capacitors or snubber circuits. Therefore, it is ideally  
suited for display applications requiring high power and mini-  
mal size.  
The LM4952 features a low-power consumption active-low  
shutdown mode. Additionally, the LM4952 features an inter-  
nal thermal shutdown protection mechanism along with short  
circuit protection.  
Applications  
n Flat Panel Monitors  
n Flat panel TV’s  
The LM4952 contains advanced pop & click circuitry that  
eliminates noises which would otherwise occur during  
turn-on and turn-off transitions.  
n Computer Sound Cards
