FEATURES  
DESCRIPTION  
The LM4865 is a mono bridged audio power amplifier  
with DC voltage volume control. The LM4865 is  
capable of delivering 750mW of continuous average  
power into an 8load with less than 1% THD when  
powered by a 5V power supply. Switching between  
bridged speaker mode and headphone (single ended)  
mode is accomplished using the headphone sense  
pin. To conserve power in portable applications, the  
LM4865's micropower shutdown mode (IQ = 0.7µA,  
typ) is activated when less than 300mV is applied to  
the DC Vol/SD pin.
