Overview
[AK09973D] AK09973D 3D Magnetic Smart Switch Sensor 1.
General Description AK09973D is a 3D magnetic smart switch sensor IC with high sensitivity and wide measurement range utilizing our latest Hall sensor technology.
Our ultra-small package of AK09973D incorporates magnetic sensors, chopper stabilized signal amplifier chain, and all necessary interface logic for detecting weak to strong magnetic fields in the Xaxis, Y-axis and Z-axis independently.
From its compact foot print, thin package, and extremely low power consumption, it is suitable for a smartphone and wearable application.
