EEVblog #600 - OpAmps Tutorial - What is an Operational Amplifier?
Why people recommend it
Dave Jones's long introduction to op-amps covering the basic rules, virtual ground, common configurations and part selection; recommended to learners who found textbook treatments hard going.
Watch for: the 'no input current' rule is an idealisation
In their words
I haven't done and studies in Op-Amp category yet but I watched a (trusted) video on Youtube and one thing is not quite logical as the next sentence: "No current flows in or out of the inputs of operational amplifier", as says Dave Jones from EEVblog on Youtube (this video: [video]).

Note: Virtual ground confuses a lot of people new to opamps; huh, why is the inverting input 0 V? (Dave's opamp video is great)

I watched Dave Jone's excellent EEVblog #600 - OpAmps Tutorial - What is an Operational Amplifier? and that I'd give it a try.
