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.
