I have a question about the input voltage range.
My circuit looks like:
I have seen, there are ESD protection diodes between the positive and negative input.
At the absolut maximum ratings I find (page 5):
Differential Input Voltage*: ±1 V
*If the differential input voltage exceeds 1 V, limit the current to 5 mA
My input signal is ue=+-2Vrms sinus and fe=0..100kHz.
Can I get problems with the ESD protection diodes on the input? Should I choose an other opv with a higher input range?
My consideration was, that the opv makes the voltage on the negativ input pin to 0V. If I have no fast changing of the input voltage, the difference between the negativ and positiv input voltage can not increase about the forward voltage of the ESD protection diodes - +-1V.
Thank you in advance.
