The sensitivity is defined by the range and the gain setting. The output of the A/D
converter is multiplied by the Gain value.

Data Sheet
The Gain value can be calculated by
For Gain values between - 0.5 and + 0.5, the numerical accuracy decreases. To obtain a flatter output curve,
a higher range setting should be selected
A Gain value of +1.0 corresponds to typical 0.8%/mT sensitivity (100 mT range, not guaranteed). It is crucial
to do a final calibration of each IC within the application using the Gain/DY
Infineon pre-calibrates the samples at zero field to 50% duty cycle (100 mT range), but does not guarantee
the value. Therefore it is crucial to do a final calibration of each IC within the application
