This configuration gives the highest input impedance of any op-amp circuit. Input impedance is equal to the differential input impedance multiplied by the open-loop gain, in parallel with common-mode input impedance. The gain error of this circuit is equal to the reciprocal of the open-loop gain or to the commonmode rejection, whichever is less.
