This 80's circuit uses an audio amplifier to obtain a symmetrical source from a single source. The maximum current is on the order of 1.3 A and the input voltage must not exceed 20 V.
This circuit is an excellent shield for microcontrollers and was found in the October 1987 Radio...
This power supply can supply voltages of 6, 9 or 12 V depending on the zener used. The maximum...
The integrated circuit used is no longer very common today, but there are still many sources that...
