2
Peak to peak value exceeded: 0.3% (6
σ
).
3
For A1373, no digital noise is present at the output.
4
Step size is larger than required for the specified range, to take into account manufacturing spread.
5
Individual code step sizes can be greater than 2× larger than the step size at each significant bit rollover.
6
Average fine code step size in a given range = (Output value at highest fine code in the range – Output value at code 0 of the range) / Total quantity of
steps (codes) in the range.
7
Values indicated are valid if any additional magnetic field does not exceed B(kG)= ±2 (V) / Sens (mv/G), after V
OUTCLP
is reached.
8
Program the
Sensitivity T/C
register before programming
Sensitivity Coarse
and
Sensitivity Fine
, due to a worst case shift of ±3% in sensitivity at 25°C
at the maximum values for
Sensitivity T/C: Positive T/C
and
Sensitivity T/C: Negative T/C
. The Programming Guidelines section in this document lists a
complete recommended order for programming individual values.
9
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
recover over time after removal from the bake.
