Ordering number : EN4592A
Thick Film Hybrid IC
STK4050V
AF Power Amplifier (Split Power Supply) (200 W min, THD = 0.08%)
Features
* Compact packaging supports slimmer set designs * Series designed from 20 up to 100 W (200 W) and pincompatibility (120 to 200 W have 18 pins) * Simpler heat sink design facilitates thermal design of slim stereo sets * Current mirror circuit application reduce distortion to 0.08 % * 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.
