Say I have a high impedance signal that is connected to an OpAmp input. My signal will on occasion go above the rails due to ringing. I expect
10V spikes against a 5V rails voltage worst case.I will leave the common mode input range of the amp, but I an okay with that. The voltage at the input also does not really go above the rail because it will get clamped by the ESD protection diodes.
Question: Is it okay to use ESD protection diode to clamp out occasional ringing in a signal? The current drive of the input signal is quite
If possible I would like to avoid an external clamp diode to protect the input. I'm dealing with high frequencies, high impedance, so the capacitance of the external diode won't be negligible.
The OpAmp in question is LT1227, just in case you want to know.
Thanks, Nils
