[1]

At a low-pass filtered analog output with a cut-off frequency of 0.7 kHz.

[2]

Definition of errors is given in Section 15.

[3]

Inhomogeneity of an 18 mm diameter disc magnet can increase the linearity error by < 0.1°.

[4]

Based on a 3σ standard deviation.

[5]

At a nominal output voltage between 5 %VDD and 95 %VDD and a maximum angle of αmax = 180°.

[6]

Room temperature is given for an ambient temperature of 25 °C.

[7]

Graph of angular error is shown in Figure 14.

[8]

In steps of resolution < 0.0027°.

[9]

Activation is dependent on the programmed diagnostic mode.

[10] Settling to these values is limited by 0.7 kHz low-pass filtering of analog output.

[11] In steps of 0.02 %VDD.

[12] At a maximum angle of αmax = 180°.

[13] Based on 12 bit.

[14] Sensor temperature refers to the on-chip temperature.
