Size and position of Hall Plates in IIS2MDC Magnetometer

[Dvon]

Hello

I want to use the IIS2MDC magnetometer in a device which measures magnetic fields that change rapidly as a function of position (e.g. fields with high gradients). For this purpose, I need to know two things which i couldn't find in the datasheet:

1. The position of the hall plates within the package LGA-12 (Section 9.1 of the datasheet of the IIS2MDC )
2. The geometrical extent of the hall sensors (for example 250um x 250 um)

Does anyone have this information, it would greatly help me!

Thanks very much

​Hi dvarx, ST magnetic sensor is not an hall sensor, but an AMR (anisotropic magnetoresistance) sensor. This is basically a Wheatstone bridge of MR resistors which are located inside the 2x2 package as describer here below.
