NOTE: As used here, negative flux densities are defined as less than zero (algebraic convention.)
Typical values are at TA = +25°C and VCC = 12 V.
1 gauss (G) is exactly equal to 0.1 millitesla (mT).
* Complete part number includes a prefix denoting operating temperature range (UGL, UGN, or UGS)
and a suffix denoting package type (LT or UA).
