A sensor arrangement comprises a plurality of magnetic field sensors (MS0 to MS15) arranged along a circularly shaped circumference (CIR1), each of the magnetic field sensors (MS0 to MS15) configured to provide a sensor signal corresponding to a magnetic field intensity. An evaluation circuit (EC) is provided comprising a plurality of input channels, each of the input channels configured to receive a digital sensor value (H0 to H15) derived from a respective one of the sensor signals. The evaluation circuit (EC) is configured to determine a rotation angle (F) as a function of a subset of the digital sensor values (H0 to H15) received. The sensor arrangement can be used with a rotatable diametrically magnetized magnetic source (MAG).
