LM4871  
1.1W Audio Power Amplifier with Shutdown Mode  
General Description  
Key Specifications  
The LM4871 is a bridge-connected audio power amplifier ca-  
pable of delivering typically 1.1W of continuous average  
n THD at 1 kHz at 1W continuous  
average output power into 8  
%
0.5 (max)  
%
power to an 8load with 0.5 (THD) from a 5V power sup-  
%
n Output power at 10 THD+N  
ply.  
1.5W (typ)  
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 LM4871 does not require  
output coupling capacitors, bootstrap capacitors, or snubber  
networks, it is optionally suited for low-power portable sys-  
tems.  
n Shutdown Current  
0.6 µA (typ)  
Features  
n No output coupling capacitors, bootstrap capacitors, or  
snubber circuits are necessary  
The LM4871 features an externally controlled, low-power  
consumption shutdown mode, as well as an internal thermal  
shutdown protection mechanism.  
n Small Outline or DIP packaging  
n Unity-gain stable  
n External gain configuration capability  
n Pin compatible with LM4861  
The unity-gain stable LM4871 can be configured by external  
gain-setting resistors.  
Applications  
n Portable Computers  
n Desktop Computers  
n Low Voltage Audio Systems
