DESCRIPTION

The LM4865 is a mono bridged audio power amplifier

with DC voltage volume control. The LM4865 is

capable of delivering 750mW of continuous average

power into an 8Ω 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 (IQ = 0.7μA,

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 fidelity. They require few external

components and operate on low supply voltages.
