1) Defined as ∆DY_PWM / ∆B, programming see Chapter 6.2.
2) Programmable in steps of 0.024%.
3) For any 1^st and 2^nd order polynomial, coefficient within definition in Chapter 8. Valid for characterization at 0 h.
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) In operating temperature range and over lifetime.
7) Measured at ±100 mT range.
