LM4865  
750 mW Audio Power Amplifier with DC Volume Control  
and Headphone Switch  
n Hand held radio  
n Other portable audio devices  
General Description  
The LM4865 is a mono bridged audio power amplifier with  
DC volume control, capable of delivering 750 mW of continu-  
ous average power into an 8load with less than 1% THD  
Key Specifications  
n PO at 1.0% THD+N into 8(SOP): 750 mW (typ)  
n PO at 10% THD+N into 8(SOP): 1W (typ)  
n Shutdown Current: 0.7 µA (typ)  
from a 5V power supply. Switching between bridged speaker  
mode and headphone (single ended) mode is accomplished  
via a headphone sense pin. In addition, LM4865 is set into  
low current consumption shutdown mode (0.7 µA typical) by  
lowering the DC Vol/SD pin to below 0.3V.  
Features  
n DC volume control  
n Headphone amplifier mode  
n “Click and pop” suppression  
n Shutdown control when volume control pin is low  
n Thermal shutdown protection  
Boomer audio power amplifiers are designed specifically to  
provide high power audio output, with quality sound, from a  
low supply voltage source while requiring the minimal  
amount of external components.  
Applications  
n GSM phones and accessories, DECT, office phones
