AF Power Amplifier (Split Power Supply)
(50W min, THD = 0.4%)
Features
• Compact package for thin-type audio sets
• Member of pin-compatible series with outputs of 20 to
200W
• Easy heatsink design to disperse heat generated in thintype stereo sets
• Constant-current circuit to reduce supply switch-on and
switch-off shock noise
• External supply switch-on and switch-off shock noise
muting, load short-circuit protection, thermal shutdown
and other circuits can be tailor-designed.

Notes.
All tests are measured using a constant-voltage supply unless otherwise specified.
1. Output noise voltage is measured using the transformer supply specified below.
2. The output noise voltage is the peak value of an average-reading meter with an rms value scale. The noise voltage waveform does not
inlcude any pulse noise.
