FEATURES  
DESCRIPTION  
The LM4881 is a dual audio power amplifier capable  
of delivering 200mW of continuous average power  
into an 8Ω load with 0.1% THD+N from a 5V power  
supply.

•
External Gain Configuration Capability  
Thermal Shutdown Protection Circuitry  
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 LM4881 does  
not require bootstrap capacitors or snubber networks,  
it is optimally suited for low-power portable systems.  
No Bootstrap Capacitors, or Snubber Circuits  
are Necessary  
APPLICATIONS  
•
•
•
Headphone Amplifier  
Personal Computers  
Microphone Preamplifier  
The LM4881 features an externally controlled, low  
power consumption shutdown mode which is virtually  
clickless and popless, as well as an internal thermal  
shutdown protection mechanism.  
KEY SPECIFICATIONS  
The unity-gain stable LM4881 can be configured by  
external gain-setting resistors.

THD+N at 1kHz at 125mW Continuous Average  
Output Power into 8Ω 0.1% (max)  
THD+N at 1kHz at 75mW Continuous  
0.02% (typ)  
Output Power at 10% THD+N at 1kHz into 8Ω  
300 mW (typ)  
•
•
Shutdown Current 0.7µA (typ)  
Supply Voltage Range 2.7V to 5.5 V
