I am using an ADC123S102QML in a high reliability application. One of the inputs is being driven by an OP470 opamp and may exceed the specified absolute maximum input voltage by Va +0.5v. The other inputs will not be exposed to an overvoltage.
Can Va + 0.5v or greater be tolerated without damage for any period of time? If so how long? What is the damage mechanism; thermal or punch-through?
Thank you.
