SBAS640A January 2018 – June 2020 DRV5055
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
Select the highest DRV5055 sensitivity option that can measure the required range of magnetic flux density, so that the output voltage swing is maximized.
Larger-sized magnets and farther sensing distances can generally enable better positional accuracy than very small magnets at close distances, because magnetic flux density increases exponentially with the proximity to a magnet.
