NTE1882
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
