产品概述
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.
