EVALUATION BOARD ELECTROSTATIC GUARDING
The guard ring is represented by the red enclosed area around
the inputs. The evaluation board uses the guard ring to
minimize leakage currents entering the inputs causing offsets.
Note that the guard ring is employed all the way from the top
copper layer through the inner layers and into the ground layer.
