High accuracy absolute Magnetic Rotary Angle Sensor

High accuracy absolute Magnetic Rotary Angle Sensor



The AK7452 is a 14bits angle sensor which detects the angular position of a magnetic field parallel to the IC surface with high speed tracking (up to 25,000rpm). The contactless angle sensor can be made by the simple construction containing small magnet and this sensor.
 The power supply voltage corresponds from 3.0 to 5.5 V, and the small package (TSSOP 16) is adopted.
Angle Error Calibration Function
The AK7452 has an angle error calibration function and it is possible to improve the accuracy by calibrating the angle error caused by mounting misalignment. Calibration is realized by writing the parameters for calibrating angle errors into the AK7452 internal EEPROM.

Various parameter setting with built-in EEPROM
With built-in EEPROM, it is possible to program zero point setting that can set any anglar position to 0 degree, rotation direction, ABZ output resolution (arbitrary value from 1 to 4096), UVW pole number (arbtray value from 1 to 32).
