, the size of the sensitive areas is greatly exaggerated for better visualization. With the trigonometric function ARCTAN2, the true 180° angle value that is represented by the relation of X and Y signals can be calculated according to
Equation (2)
. The AMR sensing element internally measures the double angle, so the result has to be divided by 2. At external magnetic angles α between 180° and 360°, the angle measured by the sensor is α - 180°. α = arctan2(Vx,Vy) / 2 (2) V VX (COS_N) VX (COS_P) 0° 45° 90° 135° 180° VMV Angle α VY (SIN_N) VY (SIN_P)
