1) Hysteresis and accuracy are depending nearly inversely proportional on the magnetic field strength. The accuracy is defined as the max.

angular difference between actual field angle and measured angle calculated from the third and fifth harmonics of the Fourier spectrum. The

hysteresis is defined as angular difference between left and right turn.

2) Generated with reference magnet 67.044 Magnetfabrik Bonn (25 kA/m @ 5.2 mm distance).

3) Minimum value depends on decreasing accuracy, upper limit on decreasing coil influence. Both are no absolute limits, but depend on the

given application requirements.

5) Reference temperature Tref = -25 °C, calculated from values at -25°C and +125 °C

6) TDFN soldered on standard test PCB, heat sink without solder connection
