SANYO STK4032II

Ordering number : EN4547A
Thick Film Hybrid IC
STK4032 II
AF Power Amplifier (Split Power Supply)
(40 W min, THD = 0.4%)
Features
Package Dimensions
• Compact packaging supports slimmer set designs
• Series designed for 20 up to 200 W and pincompatibility
• Simpler heat sink design facilitates thermal design of
slim stereo sets
• The pulse noises associated with turning the power on
and off have been reduced by the adoption of fixed
current circuits
• 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
