Product data sheet
12.1 General
12.2 Linearity error
For the accuracy is assumed that the sensor operates in a homogeneous magnetic field at
saturation field strength H
mechanical reference point at room temperature (and zero degree).
This reference line is valid for digital and analog outputs. The maximum angle is set to
180 and the clamping levels are programmed to V
The deviation from the reference line
follows:
T
Following formula is used to calculate
V
For sensors the error of the analog output
to 94.5 %V
