Typical values with +/- are 3 sigma values.

A single part will not have both the maximum/minimum sensitivity error and maximum/minimum offset voltage, as that would violate the maximum/minimum total output

error specification. Also, 3 sigma distribution values are combined by taking the square root of the sum of the squares. See Application Information section.

4

Offset Voltage does not incorporate any error due to external magnetic fields. See section: Impact of External Magnetic Fields.
