LM4876  
1.1W Audio Power Amplifier with Logic Low Shutdown  
General Description  
Key Specifications  
The LM4876 is a single 5V supply bridge-connected audio  
power amplifier capable of delivering 1.1W (typ) of continu-  
ous average power to an 8load with 0.5% THD+N.

Like other audio amplifiers in the Boomer series, the LM4876  
is designed specifically to provide high quality output power  
with a minimal amount of external components. The LM4876  
does not require output coupling capacitors, bootstrap ca-  
pacitors, or snubber networks. It is perfectly suited for low-  
power portable systems.

Features  
The LM4876 features an active low externally controlled,  
micro-power shutdown mode. Additionally, the LM4876 fea-  
tures an internal thermal shutdown protection mechanism.  
For PCB space efficiency, the LM4876 is available in MSOP  
and SO surface mount packages.  
n Does not require output coupling capacitors, bootstrap  
capacitors, or snubber circuits  
n 10-pin MSOP and 8-pin SO packages  
n Unity-gain stable  
n External gain set  
The unity-gain stable LM4876’s closed loop gain is set using  
external resistors.  
Applications  
n Mobile Phones  
n Portable Computers  
n Desktop Computers  
n Low-Voltage Audio Systems
