3) Residual sensitivity error band over temperature when using minimum 2 temperatures. Valid for 0h in dry state only. Dry is
defined after following baking process: 60minutes at T=125°C.
4) This range is also used for temperature and offset pre-calibration of the IC.
5) Depending on offset and gain settings, the output may already be saturated at lower fields.
6) INL = V_OUT - V_OUT, lse with V_OUT, lse = least square error fit of V_OUT.
Valid in the range (5% of V_DD) < V_OUT < (95% of V_DD) for TJ ≤ 105°C
7) In operating temperature range and over lifetime.
8) For Sensitivity S > 25 mV / mT. For lower sensitivities, the zero field voltage drift is dominant.
9) Measured at ±100 mT range.
