Overview

LM4875 750 mW Audio Power Amplifier with DC Volume Control and Headphone Switch January 2002 LM4875 750 mW Audio Power Amplifier with DC Volume Control and Headphone Switch General Description The LM4875 is a mono bridged audio power amplifier with DC voltage volume control.
The LM4875 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 LM4875’s micropower shutdown mode (IQ = 0.
7µA, typ) is activated when less than 300mV is applied to the DC Vol/...
