LM4865
750 mW Audio Power Amplifier with DC Volume Control and Headphone Switch
LM4865
750 mW Audio Power Amplifier with DC Volume Control
and Headphone Switch
General DescriptionThe LM4865isa mono bridged audio power amplifier with voltage volume control. The LM4865is capableof deliv-
ering 750mWof continuous average power intoan8Ω load
with less than1% THD when poweredbya5V power supply.
Switching between bridged speaker mode and headphone
(single ended) modeis accomplished using the headphone
sense pin.To conserve powerin portable applications, the
LM4865’s micropower shutdown mode(IQ= 0.7μA, typ)is
activated when less than 300mVis appliedtotheDC Vol/SD
pin.
Boomer audio power amplifiers are designed specificallyto
provide high power audio output while maintaining high fidel-
ity. They require few external components and operateon
low supply voltages.
Applications GSM phones and accessories, DECT, office phones Hand held radio Other portable audio devices
