LM4864  
300 mW Audio Power Amplifier with Shutdown Mode  
General Description  
Key Specifications  
The LM4864 is a bridged audio power amplifier capable of  
delivering 300 mW of continuous average power into an 8  
load with 1% (THD) from a 5V power supply.  
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 LM4864 does not require output coupling  
capacitors, bootstrap capacitors or snubber networks, it is  
optimally suited for low-power portable applications.  
n THD at 1 kHz at 300 mW continuous  
average output power into 8Ω  
1.0% (max)  
n THD at 1 kHz at 300 mW continuous  
average output power into 16Ω  
1.0% (max)  
0.7 µA (typ)  
n Shutdown current  
Features  
n MSOP, SOP, and DIP packaging  
The LM4864 features an externally controlled, low power  
consumption shutdown mode, and thermal shutdown protec-  
tion.  
n No output coupling capacitors, bootstrap capacitors, or  
snubber circuits are necessary  
n Thermal shutdown protection circuitry  
n Unity-gain stable  
The closed loop response of the unity-gain stable LM4864,  
can be configured by external gain-setting resistors. The de-  
vice is available in multiple package types to suit various ap-  
plications.  
n External gain configuration capability  
Applications  
n Cellular Phones  
n Personal Computers  
n General Purpose Audio
