Measured without bypass capacitor between VCC pin and the GND pin. Use of a bypass capacitor results in slower current change.

3

Measured with internal bypass capacitor (0.1 µF) between VCC and GND. Additional bypass capacitance results in slower current change.

Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north

magnetic polarity; therefore greater B values indicate a stronger south polarity field (or a weaker north polarity field, if present).

1 G (gauss) = 0.1 mT (millitesla).
