SSM2018 runs with max gain


I have a support case in where a SSM2018 output the max signal level regarles of the control voltage.

I know that the ssm2018 is obsolete since a long time, but because this concerns a medical device

I have to do a risc managment.

So my question is: Is there any experience in how often this failure has occured ?

Best regards
