5.2.5.2 Angle Calculation with end-of-line calibration values
The TLE5012B already has pre-calibrated compensation parameters which can be used to calculate the angle
value (see Chapter 5.2.5.1). Own compensation parameters can also be calculated end-of-line if desired. In that
case check the Application Note TLE5009 Calibration.
