LM4872  
1 Watt Audio Power Amplifier in micro SMD package  
General Description  
Key Specifications  
The LM4872 is a bridge-connected audio power amplifier ca-  
pable of delivering 1 W of continuous average power to an  
8load with less than .2% (THD) from a 5V power supply.  
n Power Output at 0.2% THD  
n Shutdown Current  
1 W (typ)  
0.01 µA (typ)  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. Since the LM4872 does not require  
output coupling capacitors or bootstrap capacitors. It is opti-  
mally suited for low-power portable applications.  
Features  
n micro SMD package (see App. note AN-1112)  
n 5V - 2V operation  
n No output coupling capacitors or bootstrap capacitors.  
n Unity-gain stable  
n External gain configuration capability  
The LM4872 features an externally controlled, low-power  
consumption shutdown mode, as well as an internal thermal  
shutdown protection mechanism.  
The unity-gain stable LM4872 can be configured by external  
gain-setting resistors.  
Applications  
n Cellular Phones  
n Portable Computers  
n Low Voltage Audio Systems
