  • Inquiry
  • Digi-Key
  • 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.
