LM4752
Stereo 11W Audio Power Amplifier
General DescriptionThe LM4752isa stereo audio amplifier capableof delivering
11W per channelof continuous average output powertoa load,or 7W per channel into 8Ω usinga single 24V
supplyat 10% THD+N.
The LM4752is specifically designedfor single supply opera-
tion anda low external component count. The gain and bias
resistors are integratedon chip, resultingina 11W stereo
amplifierina compact7pin TO220 package. High output
power levelsat both 20V and 24V supplies and low external
component count offer high valuefor compact stereo andTV
applications.A simple mute function canbe implemented
withthe additionofa few external components.
