Why do we say open-loop gain of op-amp is very high usually quoted in 100,000 or so,but it gets saturated for the values of Vcc?

Question

kenljw · Answer

Every amplifier. regardless of gain, have physical limits.  In electronics the maximum out is Vcc and the signal get clipped.  What this is saying the maximum input of a Opamp mentioned is Vcc/100,000 for near linear amplification.

So if I Apply 10uV as my input and hope that the op-amp is sensitive to that signal and operated in open-loop configuration.then do i get the 1v as my output?

yes, but not generally done due to noise and othe factors.  Feedback decreases noise, distortions (increases bandwidth), stabliity.

Sorry, increases stability.
