... By use of a modified atan algorithm the field angle can be calculated with high accuracy unique feature, the KMT36H is able to measure full 360° by utilizing an additional magnetic field which is generated by a planar coil that is integrated on the chip. The 180° /360° determination is done by a simple sign distinction and may be computed periodically or only once at power up ...
