Temperature range is as follows: A Versions: –40 C to +85 C.
A calibration is effectively a conversion so these errors will be of the order of the conversion noise shown in Tables I to IV. This applies after calibration at the temperature of interest.
Recalibration at any temperature will remove these drift errors.
Positive Full-Scale Error includes Zero-Scale Errors (Unipolar Offset Error or Bipolar Zero Error) and applies to both unipolar and bipolar input ranges.
Full-Scale Drift includes Zero-Scale Drift (Unipolar Offset Drift or Bipolar Zero Drift) and applies to both unipolar and bipolar input ranges.
Gain Error does not include Zero-Scale Errors. It is calculated as Full-Scale Error—Unipolar Offset Error for unipolar ranges and Full-Scale Error—Bipolar Zero Error for
bipolar ranges.
