Notes:

1.

1 Oersted (Oe) = 1 Gauss in air.

2.

See the Appendix for package dimensions and tolerances.

3.

Sensors can be provided in die form by special request.

4.

GMR A

voltages

dissipation in the package and the maximum operating temperature of the sensor.

5.

Unipolar operation means exposure to magnetic fields of one polarity, e.g., 0 to 30 Gauss, or 2 to -50 Gauss, but not -20 to

+30 Gauss (bipolar operation)

6.

TCR is resistance change with temperature with no applied field

constant current source to power the sensor

to power the sensor

7.

Beta (

β) is any angle deviation from the sensitive axis.
