Integrated Circuit

Module – AF Power Amp,

100W Min, Dual Power Supplies

Features:

D Compact packaging supports slimmer set designs

D Simpler heat sink design facilitates thermal design of slim stereo sets

D Current mirror circuit application reduces distortion to 0.08%.

D Supports addition of electronic circuits for thermal shutdown and load–short protection circuit

as well as pop noise muting which occurs when the power supply switch is turned on and off
