1) _{For VOUT within the range of 5%... 95% of VDD}
2) _{Programmable in steps of 1.22 mV ( @ VDD = 5V ).}
3) _{For small sensitivity settings. For higher sensitivities, the magnetic offset drift is dominant.}
This means that, for an example with a calibrated 60mV/mT sensitivity, the typical output drift
might be given due to the allowed magnetic offset tolerance up to ±0.5 mT x 60 mV/mT = ±30 mV @5 V V_DD.
4) _{For 4.5 V≤VDD≤5.5 V and within nominal VOUT range; see “Ratiometry” on Page 15 for details on ERAT.}
5) _{For the maximum error in the extended voltage range, see “Ratiometry” on Page 15.}
6) _{More information, see “DAC Input Interpolation Filter” on Page 22.}
7) _{100 mT range, sensitivity 60 mV/mT, LP-filter 244 Hz, 160 Hz external RC low pass filter as application circuit.}
8) _{’5% exceeded’ means that 5 of 100 continuously measured VOUT samples are out of limit.}
9) _{A sinusoidal magnetic field is applied, VOUT shows amplitude of 20% of VDD, no LP filter is selected.}
