LM4900  
265mW at 3.3V Supply Audio Power Amplifier with  
Shutdown Mode  
j
General Description  
THD+N at 1kHz for 675mW continuous  
average output power into 8,  
VDD = 5V  
The LM4900 is a bridged audio power amplifier capable of  
delivering 265mW of continuous average power into an 8Ω  
load with 1% THD+N from a 3.3V power supply.  
1.0% (max)  
0.1µA (typ)

Shutdown current  
Boomer® audio power amplifiers were designed specifically  
to provide high quality output power from a low supply volt-  
age while requiring a minimal amount of external compo-  
nents. Since the LM4900 does not require output coupling  
capacitors, bootstrap capacitors or snubber networks, it is  
optimally suited for low-power portable applications.  
Features  
n MSOP, LLP, and SOP packaging  
n No output coupling capacitors, bootstrap capacitors, or  
snubber circuits are necessary  
The LM4900 features an externally controlled, low power  
consumption shutdown mode, and thermal shutdown protec-  
tion.  
n Thermal shutdown protection circuitry  
n Unity-gain stable  
n External gain configuration capability  
n Latest generation "click and pop" suppression circuitry  
The closed loop response of the unity-gain stable LM4900  
can be configured by external gain-setting resistors.  
Applications  
n Cellular phones  
Key Specifications  
n PDA’s  
n Any portable audio application
