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)
TCR is resistance change with temperature with no applied field
constant current source to run the sensor
run the sensor.
Beta (β) is any angle deviation from the sensitive axis.

.
The output signal will be proportional to the supply voltage
sensors are pure ratiometric devices meaning that they will operate properly at extremely low supply
