We are using AD7938 CONVERTOR. The limit for analog inputs is -0.3V. In our
application we could potientially go to -0.35, if we were to limit the current
to say 3mA would this cause permanent damage?
The part won’t damage however we cannot guarantee the performance and
functionality if you are exceeding max rating specifications. It’s very good
idea to limit the current to 3 mA, because of that you shouldn’t see any
