150 W min AF Power Amplifier
(Split Power Supply)
STK4048V
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.
