AF Power Amplifier (Split Power Supply)
(120 W min, THD = 0.08%)
STK4046V
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 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.
