General
2.4 Transfer Functions
The examples in Figure 3 show how easily different magnetic field ranges can be
mapped to the output voltage.
• Polarity Mode:
– Unipolar: Only North- or South-oriented magnetic fields are measured.
– Bipolar: Magnetic fields can be measured in both orientations.
The limit points must not be symmetric to the zero field point.
• Inversion: The gain values can be set positive or negative.

Figure 3 Examples of Operation
Note: Due to the ratiometry, voltage drops at the VDD line are imaged in the output
signal.
