ADA4622-2

Dear all, 

I'm considering using  ADA4622-2 as an input buffer in a voltage follower configuration for a medical application. Op-amp will be powered in +/-5V and inputs will be connected to a patient through input resistors.   

Is there known or foreseeable failure situations where -ina, +ina, -inb or +inb pins can se shorted to V+ and V- power rails? If yes the design will need huge input resistors to limit the current to acceptable limit required by 60601-1 std. 

Please let me know you experience regarding possible ADA4622-2 op-amp fault conditions. Thank you. 

Best regards, 

Benoît,
