LM4755
Stereo 11W Audio Power Amplifier with Mute
General Description

The LM4755isa stereo audio amplifier capableof delivering
11W per channelof continuous average output powertoa loador 7Wper channel into8Ω usinga single 24V supply 10% THD+N. The internal mute circuit and pre-set gain
resistors providefora very economical design solution.
Output power specificationsat both 20V and 24V supplies
and low external component count offer high valueto con-
sumer electronic manufacturersfor stereoTV and compact
stereo applications. The LM4755is specifically designedfor
single supply operation.
