FEATURES  
DESCRIPTION  
The LM4876 is a single 5V supply bridge-connected  
audio power amplifier capable of delivering 1.1W (typ)  
of continuous average power to an 8Ω load with 0.5%  
THD+N.

•
Does Not Require Output Coupling Capacitors,  
Bootstrap Capacitors, Or Snubber Circuits  
•
•
•
10-pin VSSOP and 8-pin SOIC Packages  
Unity-Gain Stable  
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 capacitors, or  
snubber networks. It is perfectly suited for low-power  
portable systems.

•
Mobile Phones  
Portable Computers  
Desktop Computers  
Low-Voltage Audio Systems  
The LM4876 features an active low externally  
controlled, micro-power shutdown mode. Additionally,  
the LM4876 features an internal thermal shutdown  
protection mechanism. For PCB space efficiency, the  
LM4876 is available in VSSOP and SOIC surface  
mount packages.  
KEY SPECIFICATIONS  
•
THD+N at 1kHz for 1W Continuous Average  
Output Power into 8Ω 0.5% (max)  
The unity-gain stable LM4876's closed loop gain is  
set using external resistors.  
•
Output Power At 1kHz Into 8Ω with 10%  
THD+N 1.5 W (typ)  
•
•
Shutdown Current 0.01µA (typ)  
Supply Voltage Range 2.0V to 5.5 V
