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 volume control, capable of delivering 750 mW of continu-
ous average power into an 8
load with less than 1% THD
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.
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.
