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 AA-Series sensors are pure ratiometric devices meaning that they will operate properly at extremely low supply
voltages. The output signal will be proportional to the supply voltage. Maximum voltage range is limited by the power
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). Bipolar operation will increase nonlinearity and hysteresis.
6. TCR is resistance change with temperature with no applied field. TCOI is the output change with temperature using a
constant current source to power the sensor. TCOV is the output change with temperature using a constant voltage source
to power the sensor. See the graphs below.
7. Beta (? is any angle deviation from the sensitive axis.
