AD8362 input protection circuit is as shown. Two anti-pole composite diodes are set between the IN + and IN- in parallel, which can play a role of being with clamping protection. It also can avoid input of the sensor to damage the chip due to the instantaneous high voltage. Besides, the diode clamp protection circuit is designed to be placed in the pine between the DECL1 and IN +, IN- and the DECL2.
