LM4871  
3W Audio Power Amplifier with Shutdown Mode  
Check for Samples: LM4871

FEATURES  
DESCRIPTION  
The LM4871 is a mono bridged audio power amplifier  
capable of delivering 3W of continuous average  
power into a 3Ω load with less than 10% THD when  
powered by a 5V power supply (see Note). To  
conserve power in portable applications, the  
LM4871's micropower shutdown mode (IQ = 0.6µA,  
typ) is activated when VDD is applied to the  
SHUTDOWN pin.

External Gain Configuration Capability  
Pin Compatible with the LM4861  
Boomer audio power amplifiers are designed  
specifically to provide high power, high fidelity audio  
output. They require few external components and  
operate on low supply voltages from 2.0V to 5.5V.  
Since the LM4871 does not require output coupling  
capacitors, bootstrap capacitors, or snubber  
networks, it is ideally suited for low-power portable  
systems that require minimum volume and weight.

•
PO at 10% THD+N, 1kHz  
Additional LM4871 features include thermal shutdown  
protection, unity-gain stability, and external gain set.

LM4871LD: 3Ω , 4Ω Loads; 3W (typ),  
2.5 W (typ)  
Note: An LM4871LD that has been properly mounted  
to a circuit board will deliver 3W into 3Ω (at 10%  
THD). The other package options for the LM4871 will  
deliver 1.5W into 8Ω (at 10% THD). See the  
Application Information section for further information  
concerning the LM4871LD, LM4871MM, LM4871M,  
and the LM4871N.
