NOTES: 1. As used here, negative flux densities are defined as less than zero (algebraic convention) and -50 G is less than +10 G.
2. B
OPx
= operate point (output turns ON); B
RPx
= release point (output turns OFF).
3. Typical Data is at T
A
= +25°C and V
DD
= 3.0 V and is for design information only.
4. 1 gauss (G) is exactly equal to 0.1 millitesla (mT).
