http://neurophysics.ucsd.edu/courses/physics_120/FET_BJT_OpAmp_Guide.pdf WebThis says how much current is needed to drive the inputs. It can be roughly converted to an input resistance by using Ohm’s law with the supply voltage. For example: If the Ib is 170 nA (nanoamps) and the supply voltage is five volts, then Ohm’s law is 5V = 170 nA x Rin. Solving this gives about 29 megohms as the input resistance.
