I don't see the long term temperature drift in the data sheet and this device is going into a machine with a 7 year life.
Is there a graph of the drift over time?
Drift is included in the ADT7410 max accuracy specification meaning that the accuracy of the part is guaranteed to be no worse than +/-0.5C over the lifetime of the part from -40 to +105. Because there is very little self heating with ADT7410, the drift tends to be very small, typically in the order of an lsb.
What is the lifetime if this product? I have a 7 year product it is going into. One would assume it is at least that, but I have never really looked into how long companies say their semiconductors will last.
ADT7410 will last for at least 10 years provided it complies with the operating conditions outlined in the datasheet.
