Signal Processing

Data Sheet

V 1.0, 2007-06

• In the quadratic path, the difference temperature is squared and multiplied with the

TC2 value.

• Both path outputs are added together and multiplied with 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 symmetric to the zero field point. Any two points in the magnetic range can be

selected to be the end points of the output curve. The output voltage represents 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.
