Programmable angle sensor
12.3 Linearity error
The KMA210 output signal deviation from a best straight line
BSL
, with the same slope as
the reference line, is defined as linearity error. The magnetic field angle is varied at fixed
temperatures for measurement of this linearity error. The output signal deviation from the
best straight line at the given temperature is the linearity error
lin
. It is a function of the
magnetic field angle
and the temperature of the device T
amb
.
12.4 Microlinearity error
The microlinearity error
lin
is the device output deviation from 1
, if the magnetic field
angle
is changed by
= 1
.
12.5 Temperature drift error
The temperature drift
temp
is defined as the envelope over the deviation of the angle
versus the temperature range. It is considered as the pure thermal effect.
