Genaral Description
AK09970 is a 3-axis magnetic sensor IC with high sensitivity and wide measurement range utilizing our latest hall sensor technology.
Our ultra-small package of AK09970 incorporates magnetic sensors, chopper stabilized signal, amplifier chain, and all necessary interface logic for detecting weak to strong magnetic fields in the X, Y and Z planes independently. From its compact foot print, thin package, and extremely low power consumption, it is suitable for a wide range of applications such as connected home, door & window opening/close sensing, and magnetic tamper detection of IoT systems or smart meters just to name a few.
