Preliminary Data Sheet
For V
Programmable in steps of 1.22 mV ( @
For small sensitivity settings. For higher sensitivities the magnetic offset drift is dominant.
This means that for example a calibrated60mV/mT sensitivity the typical output drift
might be given due to the allowed magnetic offset tolerence up to ±0.5mT x 60 mV/mT = ±30 mV @5V Vdd.
For 4.5V
For the maximum error in the extended voltage range see chapter
More information:
100mT range, sensitivity 60mV/mT, LP-filter 244Hz, 160Hz external RC lowpassfilter as application circuit.
