Hello All,
I am going through the description of inverting operational amplifier.
The equation for output voltage is given as,
Vout/Vin = -Rf/Rg
In a way, this simply looks like a voltage divider circuit and one can get a larger voltage by keeping Rf/Rg very high. I am not able to appreciate concept of amplifier in this case.
My initial assumption was that the output would be Vout = Gain * Ve. But I dont see this description in tutorial I am reading.
Can people coment please.
PS: I am new to the world of analog
