  • Data Sheet


The AK7401 is an automotive qualified 12bits angle sensor which detects 

the angular position of a magnetic field parallel to the IC surface.

The contactless angle sensor can be made by the simple construction

containing small magnet and this sensor.


Key Features

 ■ Monolithic integrated 360 degrees angle sensor IC containing hall element 

 ■ Easy to make a contactless rotation sensor with diametrically magnetized mono-pole magnet

 ■ Interfaces:PWM / Serial interface (3 line type)

 ■ 12bit angle resolution

 ■ Less than ±0.95deg angle accuracy at 25℃ 

 ■ Over voltage protection

 ■ Reverse connect protection 

 ■ Various abnormal detection(memory data check, abnormal magnetic flux density range、and so on)

 ■ Setting function like zero point, rotation direction, memory lock etc. via serial interface.
