• Manufacturer Part Number: tle4997i
• Description: Programmable Linear Hall Sensor For Industrial Use
• Manufacturer: Infineon Technologies Corporation

• In the quadratic path, the difference temperature is squared and multiplied with the
• Both path outputs are added together to the gain value from the EEPROM.
6.1
The working range of the magnetic field defines the input range of the A to D converter.
It is always symmetric to the zero field point.
Any 2 points in the magnetic range can be selected to be the end points of the output
curve. The output voltage represents the range between them.
In 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.
