... Because the LM50’s quiescent current is less than 130 µA, self-heating is limited to a very low 0.2˚C in still air.

... Note 9: Quiescent current is defined in the circuit of Figure 1 . Note 10: For best long-term stability, any precision circuit will give best results if the unit is aged at a warm temperature, and/or temperature cycled for at least 46 hours before long-term life test begins. This is especially true when a small (Surface-Mount) part is wave-soldered; allow time for stress relaxation to occur. The majority of the drift will occur in the first 1000 hours at elevated temperatures ...

... This presumes that the ambient air temperature is almost the same as the surface temperature; if the air temperature were much higher or lower than the surface temperature, the actual temperature of the LM50 die would interme- diate temperature between the surface temperature and the air temperature. ...
