Homework Statement
This isn't necessarily a direct homework problem that I have, but it is brought up a few times in homework problems for the chapter I'm reading through in my circuits book.. It will ask me if a certain voltage exceeds the saturation (or in other problems, at what value of the input voltage does the op amp reach saturation).
I know in the cases where the opamp has a "V+" and a "V-", that those are the "bounds". If you have a V+ = 10V, and the input voltage times gain = 15V, then the output will still be 10V (in ideal circumstances, I believe that realistic applications that number is more like 85% of the V+\-)
But what about circumstances in which a V+ and V- are not given? I read something about ideal opamps have an infinite open loop gain, but I don't really understand what that is supposed to mean. It seems to me that an opamp that doesn't have those V+ and V- bounds wouldn't be limited (possibly they would be by the fact if you have thousands of volts, despite minuscule currents, you could still fry the opamp).
Any thoughts?
