Temperature ranges are as follows: A, B Versions: –40°C to +85°C; S, T Versions: –55°C to +125°C.
Apply after calibration at the temperature of interest. Full-scale error applies for both unipolar and bipolar input ranges.
Total drift over the specified temperature range since calibration at power-up at 25 °C. This is guaranteed by design and/or characterization. Recalibration at
In Unipolar mode, the offset can have a negative value (–V
The specifications for input overrange and for input span apply additional constraints on the offset calibration range.
For Unipolar mode, input span is the difference between full scale and zero scale. For Bipolar mode, input span is the difference between positive and
