(1) Drift at any temperature can be calculated from drift values at 125°C or –40°C. For example, drift at 85℃ = \((85 – 25) / (125 – 25\)) × (drift at 125℃); similarly, drift at  –20℃ = \((25 – (–20\)) / (25 – (–40\))) × (drift at –40℃).
(2) x_RANGE denotes the X_RANGE, Y_RANGE, or Z_RANGE register bits
(3) Angle measurement is performed in static condition. The input sinusoidal magnetic fields have peak magnitudes  equal to 80% of the magnetic full ranage. Offset and gain corrections have been performed at 25℃.
