Notes:
1. Large Magnetic Fields WILL NOT cause damage to NVE GMR Sensors.
2. 1 Oe (Oersted) = 1 Gauss in air = 0.1 mTesla = 79.8 Amps/meter.
3. TCOV is the percent change in output signal over temperature with a constant voltage source powering the part and TCOI
is the percent change in output over temperature with a constant current source.
