STK4050V Datasheet, PDF (1/3 Pages) Sanyo Semicon Device – AF Power Amplifier (Split Power Supply) (200 W min, THD = 0.08%)

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 pin-
compatibility (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.
