NOTES:1. Complete part number includes a suffix to identify operating temperature range (E or L) and
package type (LH, LT, or UA).
2. As used here, negative flux densities are defined as less than zero (algebraic convention) and -50 G is less than +10 G.
3. Typical Data is at T

= +25°C and V
CC
= 12 V and is for design information only.
4. 1 gauss (G) is exactly equal to 0.1 millitesla (mT).
