Magnetic flux density is measured at most sensitive area of device located 0.018" (0.46 mm) below the branded face of the “UA”
package.
* See Characteristics Definitions for test conditions.
† The nominal sensitivity temperature stability is designed to compensate for the temperature coefficient of samarium-cobalt
magnets (-0.02%/
°C).
‡ This calculation (formula 1, next page) yields the device’s equivalent accuracy, over the operating temperature range, in gauss.
