Ordering number : EN4678A
Thick Film Hybrid IC
STK4046XI
AF Power Amplifier (Split Power Supply) (120 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.
