NOTES
*B and S Versions apply to AD7817 only. For operating temperature ranges, see Ordering Guide.

See Terminology.
3
The accuracy of the temperature sensor is affected by reference tolerance. The relationship between the two is explained in the section titled Temperature Measure-
ment Error Due to Reference Error.
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 external reference is applied.
6
Refers to the input current when the part is not converting. Primarily due to reverse leakage current in the ESD protection diodes.
