This automotive circuit was obtained from an 80's schematic from the integrated circuit factory itself. The voltage regulator is still common, but the operational amplifier is of the time.
This circuit is used to test an inductor (coil) allowing the observation of its opration in an R-L...
This interesting source, obtained in a 2001 catalog, can vary the output voltage between -16 and...
This amplifier is from the 80s integrated circuit manual itself. Equivalent configurations can be adopted for...
