The thermal time constant is the time it takes for a temperature delta to change to 63.2% of its final value. For example, if the ADT7302 experiences a thermal shock
from 0°C to 100°C, it typically takes 2 seconds for the ADT7302 to reach 63.2°C.
The ADT7302 is taken out of shutdown mode and a temperature conversion is immediately performed after this write operation. Once the temperature conversion is
complete, the ADT7302 is put back into shutdown mode.
Guaranteed by design and characterization, not production tested.
