STK4038II Datasheet, PDF (1/3 Pages) Sanyo Semicon Device – AF Power Amplifier (Split Power Supply) (60 W min, THD = 0.4%)

Ordering number : EN4546A
Thick Film Hybrid IC
STK4038 II
AF Power Amplifier (Split Power Supply)
(60 W min, THD = 0.4%)
Features
Package Dimensions
• Compact packaging supports slimmer set designs
• Series designed for 20 up to 200 W and pin-
compatibility
• 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

Note: Use rated power supply for test unless otherwise specified.
1. Use the transformer power supply shown on the next page when measuring the available time for load shorted and the output noise voltage.
2. Output noise voltage represents the peak value on the rms scale (VTVM). The noise voltage waveform does not include the pulse noise.
