AF Power Amplifier (Split Power Supply)

(40 W min, THD = 0.4%)

STK4032 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.
