"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.
