Drift due to temperature cycling is due to package effects on the Hall transducer. The stress is reduced when the package is baked. However, it will

Peak to peak value exceeded: 0.3% (6σ).
For A1373, no digital noise is present at the output.
Step size is larger than required for the specified range, to take into account manufacturing spread.
Individual code step sizes can be greater than 2× larger than the step size at each significant bit rollover.
Values indicated are valid if any additional magnetic field does not exceed B(kG)= ±2 (V) / Sens (mv/G), after V
