Audio AMP + 3kHz Filter - This circuit is the audio amp section for a
complete optical transmitter. The circuit amplifies and filters the voice
audio signals from an electret microphone. The circuit is described in more
detail in the receiver section of Dave Johnson's Handbook of Optical Through the Air
Communications. (this link is off-site.) …. [Designed by David A. Johnson] |

Audio amp makes efficient fan controller - 11/09/00 EDN-Design Ideas
You can use discrete transistors to vary power to a fan to control its speed. However,
with a simple modification, you can use an audio-amplifier IC to control a fan module
(Figure 1). The LM4872….PDF contains multiple circuits, scroll to find the one of
interest.... [Design Idea by Wallace Ly, National Semiconductor Corp, Santa Clara, CA] |

Audio Amplifier - This simple amplifier shows the LM386 in a high-gain
configuration (A = 200). For a maximum gain of only 20, leave out the 10 uF connected
from pin 1 to pin 8. Maximum gains between 20 and 200 may be realized

Audio Amplifier Output Relay Delay - This is a simple circuit which I built
to one of my audio amplifier projects to control speaker output relay. The
purpose of this circuit is to control relay which turns on speaker output
relay in audio amplifier. The idea of circuit is wait around 5 seconds
after power up until speakers are switched to amplifiers....
