I am using AD8418ABRMZ amplifier for low DC voltage measurement. Op-amp single Supply voltage is 3.3VDC .
I want to add some protection circuit for ESD, transient and Surge voltages. I am planning to use TVS diodes/ varistor at the input pin of op-amp. Suggest best TVS diode or varistor for the same.
Which is good whether TVD diode or varistor and how to select it ?
