1 _{The accuracy specifications for 0°C to 70°C are specified to 3.5-Σ performance.}
2 _{It is not recommended to operate the device at temperatures above 125°C for greater than a total of 5% (5,000 hours) of the lifetime of the device. Any exposure}
beyond this limit affects device reliability.
3 _{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 ADT7301 experiences a thermal shock}
from 0°C to 100°C, it would take typically 2 seconds for the ADT7301 to reach 63.2°C.
4 _{The ADT7301 is taken out of shutdown mode and a temperature conversion is immediately performed after this write operation. When the temperature conversion is}
complete, the ADT7301 is put back into shutdown mode.
5 _{Guaranteed by design and characterization, not production tested.}
