Angle Performance

After internal angle calculation, the sensor has a remaining error, as shown in Table 3-11 for an ambient

temperature range up to 85°C and a reduced magnetic field range and in Table 3-12 for the ambient

temperature range up to 125°C and full magnetic operating range. The error value refers to BZ= 0mT.

The overall angle error represents the relative angle error. This error describes the deviation from the

reference line after zero-angle definition. It is valid for a static magnetic field.

If the magnetic field is rotating during the measurement, an additional propagation error is caused by the

angle delay time (see Table 3-9).
