Typical values with +/- are 3 sigma values.

Percentage of IP, with IP = IPR(max)

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.

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