Thermal Time Constant is the time it takes for a starting temperature difference to change to 36.8% of it’s starting value. For example if the ADT7302 experienced a
thermal shock from 0°C to 100°C, it would take typically 2 secs 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.
