TA = 25°C, and Sens(25°C)1 is the value of sensitivity at TA = 25°C
after temperature cycling TA up to 150°C, down to –40°C, and
back to up 25°C.
Linearity Sensitivity Error
The 132x is designed to provide
linear output in response to a ramping applied magnetic field.
Consider two magnetic fields, B1 and B2. Ideally the sensitivity
of a device is the same for both fields for a given supply voltage
and temperature. Linearity sensitivity error is present when there
is a difference between the sensitivities measured at B1 and B2.
Linearity Sensitivity Error is calculated separately for the positive
(LINERR+) and negative (LINERR–) applied magnetic fields. Lin-
earity Sensitivity Error (%) is measured and defined as:
SensB(++)
SensB(+)
1–
LinERR+ =
×100%
SensB(– –)
SensB(–)
1–
LinERR– =
×100%
(7)
and
LinERR = max(|LinERR+| , |LinERR–| )
(8)
where:
|VOUT(Bx) – VOUT(Q)|
BX
SensBx =
(9)
and B(++), B(+), B(– –), and B(–) are positive and negative mag-
netic fields with respect to the quiescent voltage output such that
|B(++)| > |B(+)| and |B(– –)| > |B(– )| .
Symmetry Sensitivity Error
The magnetic sensitivity of a
device is constant for any two applied magnetic fields of equal
magnitude and opposite polarities.
Symmetry Error (%), is measured and defined as:
SensB(+)
SensB(–)
1–
SymERR =
×100%
(11)
where SensBx is defined as in equation 9, and B(+), B(–) are posi-
tive and negative magnetic fields such that |B(+)| = |B(–)|.
Ratiometry Error
The A132x features a ratiometric output.
This means that the quiescent voltage output, VOUT(Q), magnetic
sensitivity, Sens, and clamp voltages, VCLPHIGH and VCLPLOW,
are proportional to the supply voltage, VCC. In other words, when
the supply voltage increases or decreases by a certain percent-
age, each characteristic also increases or decreases by the same
percentage. Error is the difference between the measured change
in the supply voltage, relative to 5 V, and the measured change in
each characteristic.
The ratiometric error in quiescent voltage output, RatVOUT(Q)
(%), for a given supply voltage, VCC, is defined as:
VOUT(Q)VCC VOUT(Q)5V
VCC
V
1–
RatVOUT(Q) =
×100%
(12)
The ratiometric error in magnetic sensitivity, RatSENS (%), for a
given supply voltage, VCC, is defined as:
SensVCC Sens5V
VCC
V
1–
RatVOUT(Q) =
×100%
