3-axis Electronic Compass
1. General Description
AK09916 is 3-axis electronic compass IC with high sensitive Hall sensor technology.
Small package of AK09916 incorporates magnetic sensors for detecting terrestrial magnetism in the X-axis,
Y-axis, and Z-axis, a sensor driving circuit, signal amplifier chain, and an arithmetic circuit for processing
the signal from each sensor. Self-test function is also incorporated. From its compact foot print and thin
package feature, it is suitable for map heading up purpose in Smart phone to realize pedestrian navigation
function.
