6.2
The overall sensitivity is defined by the range and the gain setting. The output of the ADC
is multiplied with 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, it is advisable to select a higher range setting
A gain value of +1.0 corresponds to typical 32 LSB
crucial to do a final calibration of each IC within the application using the Gain/OUT
Infineon pre-calibrates the samples at zero field to 50% output value (100 mT range), but does not guarantee
the value. Therefore it is crucial to do a final calibration of each IC within the application
