Newbie level 6
Hi, I was wondering if designing a circuit for constant, flat, gm means it has to be designed as well for constant,flat, gain. And if the isn't kept constant rail to rail, then what is the industry set standard on the quality of the changing open loop gain? (THD+N?). Also are there any sort of data in the data sheet of opamps that at least indirectly tell us the how much the open loop gain of the amplifier changes with input common mode level? I can't seem to find graphs like output voltage accuracy(which would reveal gain) vs. input common mode level in the analog devices data sheet. Anyway, any help is greatly appreciated.
