NOTE 1 – Magnetic flux density is measured at most sensitive area of device located 0.018" (0.46 mm) below the
branded face of the package.
NOTE 2 – 10 G = 1 mT, exactly.
NOTE 3 – Except for ∆Sens(∆T), typical data is at TA = 25°C and is for design information only.
* See Characteristics Definitions for test conditions.
† This calculation (formula 1, next page) yields the device’s equivalent accuracy, over the operating temperature range, in
gauss.
