FEATURES  
DESCRIPTION  
The LM4811 is a dual audio power amplifier capable  
of delivering 105mW per channel of continuous  
average power into a 16load with 0.1% (THD+N)  
from a 5V power supply.

Digital Volume Control Range from +12dB to  
33dB  
WSON and VSSOP Surface Mount Packaging  
"Click and Pop" Suppression Circuitry  
No Bootstrap Capacitors Required  
Low Shutdown Current  
Boomer audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. Since the  
LM4811 does not require bootstrap capacitors or  
snubber networks, it is optimally suited for low-power  
portable systems.  
APPLICATIONS  
Cellular Phones  
MP3, CD, DVD Players  
PDA's  
The LM4811 features a digital volume control that  
sets the amplifier's gain from +12dB to 33dB in 16  
discrete steps using a twowire interface.  
Portable Electronics  
The unity-gain stable LM4811 also features an  
externally  
controlled,  
active-high,  
micropower

consumption shutdown mode. It also has an internal  
thermal shutdown protection mechanism.
