LM4861  
1.1W Audio Power Amplifier with Shutdown Mode  
General Description  
Key Specifications  
The LM4861 is a bridge-connected audio power amplifier ca-  
pable of delivering 1.1W of continuous average power to an  
8load with 1% (THD) using a 5V power supply.  
n THD at 1 kHz at 1W continuous  
average output power into 8Ω  
1.0% (max)  
1.5W (typ)  
0.6 µA (typ)  
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 using surface mount packaging. Since  
the LM4861 does not require output coupling capacitors,  
bootstrap capacitors, or snubber networks, it is optimally  
suited for low-power portable systems.  
n Shutdown Current  
Features  
n No output coupling capacitors, bootstrap capacitors, or  
snubber circuits are necessary  
The LM4861 features an externally controlled, low-power  
consumption shutdown mode, as well as an internal thermal  
shutdown protection mechanism.  
n Small Outline (SO) packaging  
n Compatible with PC power supplies  
n Thermal shutdown protection circuitry  
n Unity-gain stable  
The unity-gain stable LM4861 can be configured by external  
gain-setting resistors.  
n External Gain Configuration Capability  
Applications  
n Personal computers  
n Portable consumer products  
n Self-powered speakers  
n Toys and games
