Exceed Input Common Mode Voltage

Dear Engineers,

 

i need your experience with the IVR of OpAmps.

Below you can find the specifications and the max ratings of the ADA4817.

IVR Ratings.png

The maximum peak voltage of the processed signal is around +5.7V (worst case). VCC is 7V, so the IVR is exceeded with 1.5V.

In this case the OpAmp output runs nonlinear (not critical).

With a VCM of 5.7V, the absolute maximum ratings are not exceeded but the maximum IVR...so can this lead to a damage of the device?

 

I have absolutely no experience with this problem...

 

Thanks for your help!

Best regards
