12bit Angle Sensor
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.
■ 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.
