Ordering number : EN4621A
Thick Film Hybrid IC
STK4040XI
AF Power Amplifier (Split Power Supply) (70 W min, THD = 0.008%)
Features
•Compact packaging supports slimmer set designs
•Series designed from 50 up to 150 W and pincompatibility
•Simpler heat sink design facilitates thermal design of slim stereo sets
•Current mirror circuit, cascade circuit and purecomplimentary circuit application reduce distortion to 0.008 %
•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.
