In this video I will briefly be discussing the Operational Amplifier and it’s functions.
I will be covering the basic configurations that may be used in out power supply design.
This is by no means an exhaustive lesson on OPAMP’s, that would take many hours of video footage and knowledge that I do not possess at this point in time, but it should be sufficient enough to allow a beginner to start using them in circuits.
Aol is the gain of the OPAMP
Vout = -(Rf/Ri)*Vin
Multi-Channel / Summing Amplifier
further stages can be added if needed, just add them at the end of the formula.
Unity Gain / Buffer
