11 _{The Mismatch between X or Y and Z can be reduced through the calibration of the SMISM (or k) factor in the end application.}
See section 17.3.2 for more information
12 _{The Magnetic Angle Phase error X or Y and Z can be reduced through the calibration of the ORTH_B1B2 factor in the end}
application. See section 17.3.2 for more information
13 _{The Intrinsic Linearity Error is a consolidation of the IC errors (offset, sensitivity mismatch, phase error) taking into account an}
ideal rotating field. Once associated to a practical magnetic construction and the associated mechanical and magnetic
tolerances, the output linearity error increases.
14 _{The Intrisic Linearity Error for Magnetic Angle ∠XZ, ∠YZ can be reduced through the programming of the SMISM (or k) factor}
and ORTH_B1B2. By applying the correct compensation, a non linearity error of +/-1 deg can be reached. See section 17.3.2 for
