LM386 isn't an op amp.
An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.
Having gain 200 LM386 can't be called op-amp
Are you surprised?
Not at all,
show me LM386 with open loop configuration.
An ideal op-amp is usually considered to have the following properties, and they are considered to hold for all input voltages:Infinite open-loop gain (when doing theoretical analysis, a limit may be taken as open loop gain AOL goes to infinity).
If there is no LM386 with open loop configuration, than you shouldn't bring this argument (open/ close loop ) in discussion. It's not related.
It was to show you that the 200x gain for lm386 is closed loop gain.
What is "operational" means, that you can design a feedback (negative/positive) in a variety ways, to create any math "operation" - differential, integral or proportional.
The higher gain, the easier it could be done.
Device with low gain is not "operational". Just amplifier.
Every opamp has gain < 1.0x
Take some good EE101 will help.
Name your favorite opamp and I will show you how to get it to <1x (open or closed loop) gain.
