3. Typical Data is at T
1. Complete part number includes a suffi x to identify operating temperature range (E or L) and package type (LH, LT, or UA).
2. As used here, negative fl ux densities are defi ned as less than zero (algebraic convention) and -50 G is less than +10 G.
3. Typical Data is at TA = +25°C and VCC = 12 V and is for design information only.
4. 1 gauss (G) is exactly equal to 0.1 millitesla (mT).
