The KMT37 is a magnetic field sensor based on the anisotropic
magneto resistance effect, i.e. it is sensing the magnetic field
direction independently on the magnetic field strength for applied
field strengths H[gt]=14 kA/m. The sensor contains two parallel
supplied Wheatstone bridges, which enclose a sensitive angle of
45 degrees.
A rotating magnetic field in the surface parallel to the chip (x-y plane)
will deliver two independent sinusoidal output signals, one
following a cosinus and the second following a sinus-function,
being the angle between sensor and field direction.
