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

V
The V
Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
Power-Up Time is measured without and with bypass capacitor of 0.01 μF. Adding a larger bypass capacitor would cause longer Power-Up Time.
Guaranteed by characterization and design.
Power-Up State as defined is true only with a V
For t > t
Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north
1 G (gauss) = 0.1 mT (millitesla).
CC
A1156, A1157, and A1158
represents the generated voltage between the VCC pin and the GND pin.

slew rate must exceed 600 mV/ms from 0 to 3 V. A slower slew rate through this range can affect device performance.
