Introduction

AK09973D is a 3D magnetic smart switch sensor IC with high sensitivity and wide measurement range utilizing latest Hall sensor technology. The 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 X-axis, 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.
