Hello everyone,
What should I do to determine the input impedence of an opamp? I want to find the input impedence of a noninverting amplifier and it is the same as that of the opamp. I know to measure various parameters like slew rate and offset voltage, but I can't find anything on Input impedence. I know it's in the datasheet, about a few megaohms, but what circuit can I use to determine it?
Thank you in advance
