AH4930Q Magnetic Characteristics
(Notes 10 and 11) (TA = +25°C, VDD = 3.3V, unless otherwise specified.) Standard convention for representing the direction of magnetic field strength and flux density by positive and negative signs is as follows: A positive field is considered as South-Pole facing the corresponding Hall element and Figure 2 shows the definition of magnetic directions X, Y, Z of the AH4390Q.

Typical data is at TA = +25C, VDD = 3.3V. 11. Maximum and minimum parameter values over operating temperature range are not tested in production; they are guaranteed by design. The magnetic characteristics may vary with supply, operating temperature and after soldering. 12. Not subject to production test, verified by design/characterization.
