1
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癈 to 100癈, it typically takes 2 seconds for the ADT7302 to reach 63.2癈.
2
The ADT7302 is taken out of shutdown mode and a temperature conversion is immediately performed after this write operation. When the temperature conversion is
complete, the ADT7302 is put back into shutdown mode.
3
Guaranteed by design and characterization, not production tested.
