AD7357 AD7356 AD7352 Offset/Gain Error Drift

Hello Everyone,


in the datasheets of the AD7357 AD7356 and AD7357 there is no information about an offset or gain error drift (over temperature). But the Positive Full-Scale Error and the Negative Full-Scale Error is defined.


Is any temperature drift included in the Positive and Negative Full-Scale Error? Can I cool down for example the AD7357BRUZ to -40°C and warm it up to +85°C, and the offset and gain error are equal or below the Positive and Negative Full-Scale Error?


To get the overall error, do I have to add the INL to the Full-Scale Error, or ist the INL part of the Full-Scale Error?
