STK4028II pdf
Ordering number : EN4548A
Thick Film Hybrid IC
STK4028 II
AF Power Amplifier (Split Power Supply)
(30 W min, THD = 0.4 %)
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.
