Linearity Error is calculated separately for the positive
(Lin
ERRPOS
) and negative (Lin
ERRNEG
) applied magnetic fields.

Then:

ERR

Note that unipolar devices only have positive linearity error
(LIN
ERRPOS
).
Symmetry Sensitivity Error The magnetic sensitivity of an
A1354 device is constant for any two applied magnetic fields of
equal magnitude and opposite polarities. Symmetry error,
Sym
ERR
(%), is measured and defined as:

where Sens
Bx
is as defined in equation 11, and BPOS and BNEG
are positive and negative magnetic fields such that |BPOS| =
|BNEG|. Note that the symmetry error specification is only valid
for bipolar devices.
Jitter The duty cycle of the PWM output may vary slightly over
time despite the presence of a constant applied magnetic field and
a constant carrier frequency for the PWM signal. This phenom-
enon is known as jitter, Jitter
PWM
(%), and is defined as:

where D
Bmax
and D
Bmin
are the maximum and minimum duty
cycles measured the over 1000 PWM clock periods with a con-
stant applied magnetic field.
Resolution The ability to derive the value of the applied mag-
netic field from the device output is affected by jitter. The resolu-
tion of the magnetic field, RES
PWM
(G), is defined as:
