ADG411 Usage

Hello, just a quick one, what is the normal operation temperature of the ADG411 component with a power rail +/- 12V?
Explanation, I have a device (which is down) that uses 2 of these components. The first heater at about 94°C and the other at 58°C.
My question: I suspect that the first is dead (more or less) what do you think?
Thank you

  • So, sorry, I was too fast in my question!

    In fact the equipment is powered by + 12V and -12V, the -12V comes from 12V via a buck power supply. It is out of order.

    I remove the circuits that composes it and connect a lab supply on the -12V.

    The AD411 no longer heats or more moderately to 33 ° C.Then the device work fine !

    Another question : With missing -12V does the AD411 go to Latch-up process ?

    Sorry and thanks.
