Description
The AK8910A is a 3-axis electronic compass IC with high sensitive Hall sensor technology. It is designed with a small package that incorporates magnetic sensors for detecting terrestrial magnetism in the X-axis, Y-axis, and Z-axis. This IC also includes a sensor driving circuit, signal amplifier chain, and an arithmetic circuit for processing the signal from each sensor. Additionally, it features a self-test function and can be used for map heading up purposes in GPS-equipped cell phones to realize pedestrian navigation functions.
