Thick Film Hybrid IC
STK4032X
AF Power Amplifier (Split Power Supply)
(40W min, THD = 0.008%)
Features
• Compact package for thin-type audio sets
• Member of pin-compatible series with outputs of 30 to
100W
• Easy heatsink design to disperse heat generated in thintype stereo sets
• Current mirror circuit for low 0.008% total harmonic
distortion
• External supply switch-on and switch-off shock noise
muting, load short-circuit protection, thermal shutdown
and other circuits can be tailored-designed.

Notes.
All tests are measured using a constant-voltage supply unless otherwise specified.
1. Available time for load short-circuit and output noise voltage are 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.
