Specification
3.6.3 GMR Parameters after Calibration
After calibration under the conditions specified in Table 9 “GMR test calibration conditions at IFX” on Page 19,
the sensor has a remaining error as shown in Table 10.
The error value refers to B_Z = 0 mT and operating conditions given in Table 3 “Operating Range” on Page 14.

1) For 4-MhHz input frequency
2) t_upd = 8192 / (25 x f_CLK) for FIR_BYP = 0
t_upd = 8192 / (100 x f_CLK) for FIR_BYP = 1
3) t_settle = 2 x t_upd , after change of ADC input source
4) Output values are valid up to this limit. Above it, corrupted results may occur due to non-linearity of the ADC.
5) One digit typically represents 5.166 µV
6) Corresponds to max. GMR output value
