Overview
LM4865 750 mW Audio Power Amplifier with DC Volume Control and Headphone Switch December 1999 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 continuous average power into an 8Ω 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.
