7.1.1 Select the Sensitivity Option

Select the highest TMAG5273 sensitivity option that can measure the required range of magnetic flux density so that the ADC input range 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. TI created an online tool to help with simple magnet calculations under the TMAG5273 product folder on ti.com.
