This very low current circuit with the ICM7860 was found in the April 1995 Electronics Now magazine. The output voltage depends on the input voltage.
This circuit uses a Norton operational amplifier to generate 1 kHz pulses with a 1 to 60...
This is one of the many versions of amplifiers with LM386. This was achieved in an old publication (1981). The...
In a voltage follower the voltage gain is unity. The input impedance is high and the output...
