LAYOUT CONSIDERATIONS<br />
Besides keeping all components that may contain ferrous materials (nickel, etc.) away from the sensor on both sides of<br />
the PCB, it is also recommended that there is no conducting copper under/near the sensor in any of the PCB layers. See<br />
recommended layout below. Notice that the one trace under the sensor in the dual supply mode is not expected to carry<br />
active current since it is for pin 4 pull-up to VDDIO. Power and ground planes are removed under the sensor to minimize<br />
possible source of magnetic noise. For best results, use non-ferrous materials for all exposed copper coding.<br />
