The condition must be fulfilled for at least one field BX or BY.

Above 70 mT, the IMC® starts saturating yielding to an increase of the linearity error.

Below 20 mT, the performances slightly degrade due to a reduction of the signal-to-noise ratio, signal-to-offset ratio.

This is the magnetic gain linked to the Integrated Magneto Concentrator (IMC®) structure. It applies to BX and BY and not to

BZ. This is the overall variation. Within one lot, the part to part variation is typically ± 10% versus the average value of the IMC®

gain of that lot
