12.4 Microlinearity
Microlinearity is the deviation between the device output and the reference line at any
angle and for an angle step of 1 . The microlinearity is determined at a constant
temperature.
The microlinearity is calculated as follows:
V
V
m
The output slopes are monotonic by design. This figures can also be used for the
definition of
V
