3 Glossary of Terms
• Gauss (G), Tesla (T): Magnetic flux density units where 1 mT = 10 G.
• Triais
®
: This technology refers to the Melexis Hall technology which allows the realization
of Hall effect sensors able to sense the flux density along the 3 axis (i.e. X, Y & Z). In
particular, it enables the realization of position sensors able to sense the magnetic flux
density parallel to the IC surface and consequently the magnetic vector over 360 degrees.
• IMC: Integrated Magneto Concentrator. It concentrates the magnetic flux lines and bends
them at the extremity under the planar Hall plates. Furthermore, it provides some magnetic
gain factor.

From the previous table and the ageing data, the intrinsic angular linearity error (in Degree)
can be derived from the individual contributions as it follows:
Test Conditions Parameters
Output Swing
Unit
± 1 V ± 2 V
Room Temperature
(T
A

Offset ± 0.8 ± 0.4 Degree
Sensitivity Mismatch ± 0.84 ± 0.84 Degree
Phase Mismatch ± 1 ± 1 Degree
Total ± 2.64 ± 2.24 Degree
Temperature Range

Offset ± 0.8 ± 0.4 Degree

Total ± 1.26 ± 0.86 Degree
Lifetime/Ageing
(HTOL 1000 hours – 5.0 V –
150 Deg.C.)
Offset ± 0.8 ± 0.4 Degree
Sensitivity Mismatch ± 0.1 ± 0.1 Degree
Phase Mismatch ± 0.1 ± 0.1 Degree
Total ± 1.00 ± 0.60 Degree
Overall Linearity Error
Excl. Ageing ± 3.90 ± 3.10 Degree
Incl. Ageing ± 4.90 ± 3.70 Degree
The intrinsic linearity error refers only to the linearity error associated to the MLX91204. The
linearity error associated to the magnetic and mechanical (off-axis, excentricity) design is not
included and should be considered as an additional contribution.
For more information, please refer to the application note:

The total error can be reduced either statically (room temperature compensation) or
dynamically (continuous compensation) through the off-chip signal processing performing the
angular computation i.e. arctan(Y_
OUT
/X_
OUT
). The compensation is applied prior to computing
the arctangent function: offset, gain and phase correction can be applied.
