ADT7420 reportable temperature range

I’m thinking of trying the ADT7420 as an alternative to the ADT7410 in a current design.  The datasheet for the ADT7420 specifies a minimum temperature of -40 degrees Celsius.  Does anyone know if this the lowest reportable temperature?  I.e. will the ADT7420 output a code to represent a temperature below -40.  I’m interested in reporting temperatures down to -55.  If anyone has experience of this I would be interested in what you found.
