20_W_AUDIO_AMPLIFIER

Published:2009/7/9 2:20:00 Author:May | From:SeekIC

This amplifier delivers 20 W into an 8-Ω load using a single IRF520 driving a transformer coupled output stage．This circuit is similar to the audio output stage used in many inexpensive radios and phonographs．Distortion is less than 5％ at 10 W，using very little feedback （3％），with the IRF520 biased at 3 A．
