• The temperature is normalized by subtraction of the reference temperature T
• The linear path is multiplied with the TC
• In the quadratic path, the temperature difference to T
• Both path outputs are added together and multiplied with the Gain value from the

The working range of the magnetic field defines the input range of the A/D converter. It
is always symmetrical around the zero field point. Any two points in the magnetic field
range can be selected to be the end points of the output value. The output value is
represented within the range between the two points.
In the case of fields higher than the range values, the output signal may be distorted. In
case of synchronous mode and ID selection mode the range must be set accordingly
(R=0/1/3) before the calibration of offset and gain.
