Hi
I am designing a tool which uses the lmp7721, and in normal operation the amplifier will not exceed the rails(obviously) but in a fault condition it may be possible for there to be 10V on the input. This obviously will not do, however I cannot add an external diode clamp or protection because that would compromise the low impedance of the amplifier. I am trying to figure out what resistance would be required on the input to allow the built in esd structure to protect the amplifier in this case, would limiting the current to 1mA or 0.1mA be sufficient?
