INPUT PROTECTION PRECAUTIONS
An input resistor (resistor RIN of Figure 21a) is recommended in
circuits where the input common-mode voltage to the AD827
may exceed (on a transient basis) the positive supply voltage.
This resistor provides protection for the input transistors by
limiting the maximum current that can be forced into their bases.

For high performance circuits, it is recommended that a second
resistor (RB in Figures 21a and 22a) be used to reduce bias-
current errors by matching the impedance at each input. This
resistor reduces the error caused by offset voltages by more than
an order of magnitude.
