LM4861  
1.1W Audio Power Amplifier with Shutdown Mode

FEATURES  
DESCRIPTION  
The LM4861 is a bridge-connected audio power  
amplifier capable of delivering 1.1W of continuous  
average power to an 8Ω load with 1% THD+N using  
a 5V power supply.  
2
No output coupling capacitors, bootstrap  
capacitors, or snubber circuits are necessary  
Small Outline (SOIC) packaging  
Compatible with PC power supplies  
Thermal shutdown protection circuitry  
Unity-gain stable  
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.  
External gain configuration capability  
APPLICATIONS  
Personal computers  
Portable consumer products  
Self-powered speakers  
Toys and games  
The LM4861 features an externally controlled, low-  
power consumption shutdown mode, as well as an  
internal thermal shutdown protection mechanism.  
The unity-gain stable LM4861 can be configured by  
external gain-setting resistors for differential gains of  
up to 10 without the use of external compensation  
components. Higher gains may be achieved with  
suitable compensation.  
KEY SPECIFICATIONS  
THD+N for 1kHz at 1W continuous average  
output power into 81.0% (max)  
Output power at 10% THD+N at 1kHz into 8Ω  
1.5 W (typ)  
Shutdown Current 0.6µA (typ)
