LM4865
750 mW Audio Power Amplifier with DC Volume Control
and Headphone Switch
General Description
The LM4865 is a mono bridged audio power amplifier with
DC voltage volume control. The LM4865 is capable of deliv-
ering 750mW of continuous average power into an 8
load
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 (I
Q = 0.7A, typ) is
activated when less than 300mV is applied to the DC Vol/SD
pin.
Boomer audio power amplifiers are designed specifically to
provide high power audio output while maintaining high fidel-
ity. They require few external components and operate on
low supply voltages.
