hey everyone, im confused on the gain quantities of the 741 op amp. Im so confused im having trouble figuring out how to even ask this.
I know the open loop gain is 100,000. But theres also different gains at different frequencies after the cutoff frequency on a bode plot. So in a plot, you would draw the midband gain as 100,000 then when you hit the bandwith point, it decreases until you hit the unity gain frequency. Whats the difference between these gains?
When solving problems, the closed loop gain I calculate via formula for inverting and non inverting configurations is the midband gain in a bode plot, then we do the same thing as with the open loop op amp 741.
Why is the gain we calculate always the midband gain when we have all these different gains at different frequencies?
