(1) Use only up to 90% of the linear magnetic range in the application
(2) Temperature drift is specified for full operating temperature range of –40°C to 125°C. Drift at an intermediate temperature can be estimated using the following examples: drift at 85°C = ((85 – 25) / (125 – 25)) × (drift); similarly, drift at  –20°C = ((25 – (–20)) / (25 – (–40))) × (drift).
(3) Angle calculation is performed on-axis after calibrating system mechanical errors including magnet tilt and magnet misalignment.
