(1) Unless otherwise stated, test conditions are as follows: Power Supply = 12VDC, Ambient Temp = 25°C,

Set/Reset switching is active

(2) Units: 1 gauss = 1 Oersted (in air) = 79.58 A/m = 10E5 gamma

(3) Transient protection circuitry should be added across V+ and Gnd if an unregulated power supply is used.
