Notes:
1. The accuracy of the transducer is defined as the maximum difference between the actual
measured magnetic flux density
and that given by the transducer.
2. The output of the measurement channel has two terminals and the output signal is the
(differential) voltage between
these two terminals.
3. Sensitivity is given as the nominal slope of an ideal linear function.
4. Nonlinearity is the deviation of the function Bmeasured = f(Bactual) from the best linear fit of this function.
5. The planar Hall voltage is the voltage at the output of a Hall transducer produced by a
magnetic flux density vector co-planar with the Hall plate.
6. This is the 6-sigma peak-to-peak span of offset fluctuations with sampling time Δt = 0.05s
and total measurement time t = 100s.
