This paper describes how to reduce the risk of damage to operational amplifiers due to excessive input current caused by forward bias of internal ESD protection diodes over a certain period of time(either long or short).In system design,adding an overvoltage protection(OVP)circuit at the input of the operational amplifier is generally solved by combining an appropriate input overvoltage protection network with an operational amplifier without integrated input overvoltage protection.
