There is a need to operate this device at -40 Celsius.

In Dubai??

Tell us more about your application.

Heating the application is one solution, but might need lots of energy. Put the circuit into a thermally insulated box and start to dissipate sufficient heat within the box (on the pcb, e.g.) whenever the temperature falls below a certain threshold.
