This is a channel of a stereo amplifier and small power with the LM386 suggested by the Radio Electronics Experimenters in the 1981 edition. The power of a few Watts.
We found this circuit in a 1997 documentation. It can be used in any common 12 V source and has...
In the figure we show how to use one of the four comparators in the LM336 in a temperature alarm. As...
We found this configuration in the ON Semiconductor thyristor manual. The triacs depend on the...
