AF Power Amplifier (Split Power Supply)
(20 W min, THD = 0.08%)
STK4024V
Features
• Compact packaging supports slimmer set designs (up
to 70 W)
• 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 reduces 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
