AF Power Amplifier (Split Power Supply)
(60 W min, THD = 0.4%)
STK4038
II
Features
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.
