A
= 85°C maximum and
temperature sensor measurement error = ±3°C maximum.
2
See the Terminology section.
3
Refers to the input current when the part is not converting. Primarily due to reverse leakage current in the ESD protection diodes.
4
Sample tested during initial release and after any redesign or process change that may affect this parameter.
5
On-chip reference shuts down when an external reference is applied.
6
The accuracy of the temperature sensor is affected by reference tolerance.
