ADT7420 Temperature Range

I want to ask a question to the Analog Devices engineers - what will happens with ADT7420 in case of operating at temperatures below -40 centigrade (-55..-40) ?

Will the device become permanently damaged (even a small possibility), or it just will give wrong results?


I have both the ADT7410 and ADT7420 devices in my design working together. Main goal - achieve wider temperature range with less accuracy at lower temperatures. So, should I physically disconnect power/signal lines of the ADT7420 at temperatures below -40 centigrade?


Thank you.
