LM4875
750 mW Audio Power Amplifier with DC Volume Control
and Headphone Switch
General Description

The LM4875isa mono bridged audio power amplifier with voltage volume control. The LM4875is 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
LM4875’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
Key Specifications
