Signal Processing
• The linear path is multiplied by the TC₁ value
• In the quadratic path, the temperature difference to T₀ is squared and multiplied by the
TC₂ value
• Both path outputs are added together and multiplied by the Gain value from the
EEPROM

Magnetic Field Ranges
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 wihtin the range between the two points.
In the case of fields higher than the range values, the output signal may be distorted.
The range must be set before the calibration of offset and gain.
