... The HMC1501 contains a single saturated-mode Wheatstone bridge sense element that creates an output voltage with respect to the direction of the magnetic flux passing over the sensor surface. The HMC1512 contains dual saturated-mode Wheatstone bridge elements co-located to provide an extended range of angular displacements. Both sensor types are cost effective and space-efficient solutions for high volume OEM designs ...

... The HMC1501 contains one bridge and the HMC1512 has two identical bridges, coexisting on a single die. Bridge B is physically rotated 45° from bridge A. The HMC1501 has a sensor output Vb*S sin (2 ), and the HMC1512 has a sensor output Vb*S sin (2 ) for sensor A and sensor B’s output -Vb*S cos (2 ) ...

... HMC1501/1512 Using the HMC1512 bridge A signal output plotted versus theta, the figure below depicts the two-cycle waveform. As you can see above, the most linear range for this sensor bridge is in the 45° range about the –180, -90, 0, 90, and 180 degree points. Of these the 0 and 180 points have a positive slope, and the 90 points have a negative slope. These slopes can be taken to full advantage for angular and linear positioning applications ...
