Symmetry Sensitivity Error The magnetic sensitivity of an 
A136x device is constant for any two applied magnetic fields of
equal magnitude and opposite polarities.
Symmetry error, Sym
ERR
 (%), is measured and defined as:
Sens
BPOS
Sens
BNEG
1

where Sens
Bx
 is as defined in equation 4, and B
POS
 and B
NEG
 are
positive and negative magnetic fields such that |B
POS
| = |B
NEG
|.
Note that the symmetry error specification is only valid for bipolar
devices.
Ratiometry Error The A136x devices feature ratiometric output. 
This means that the quiescent voltage output, V
OUT(Q)
, magnetic
sensitivity, Sens, and clamp voltage, V
CLP(HIGH)
 and V
CLP(LOW)
,
are proportional to the supply voltage, V
CC
. 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, Rat
ERRVOUT(Q)
 
(%), for a given supply voltage, V
CC
, is defined as:
V
OUT(Q)(VCC)
