LM4862  
675 mW Audio Power Amplifier with Shutdown Mode  
General Description  
Key Specifications  
The LM4862 is a bridge-connected audio power amplifier ca-  
pable of delivering typically 675 mW of continuous average  
power to an 8load with 1% (THD) from a 5V power supply.  
n THD at 500 mW continuous average  
output power at 1 kHz into 8Ω  
1% (max)  
n Output power at 10% THD+N at  
1 kHz into 8Ω  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. Since the LM4862 does not require  
output coupling capacitors, bootstrap capacitors, or snubber  
networks, it is optimally suited for low-power portable sys-  
tems.  
825 mW (typ)  
0.7 µA (typ)  
n Shutdown Current  
Features  
n No output coupling capacitors, bootstrap capacitors or  
snubber circuits are necessary  
n Small Outline or DIP packaging  
n Unity-gain stable  
n External gain configuration capability  
n Pin compatible with LM4861  
The LM4862 features an externally controlled, low-power  
consumption shutdown mode, as well as an internal thermal  
shutdown protection mechanism.  
The unity-gain stable LM4862 can be configured by external  
gain-setting resistors.  
Applications  
n Portable Computers  
n Cellular Phones  
n Toys and Games
