Offset Definition
The offset of the X and Y signals is defined as the mean value between the signed maximum and minimum values
of the idealized sine or cosine wave.
Amplitude Definition
The amplitude is defined as half the difference between the signed maximum and minimum values of the idealized
sine or cosine wave.
Temperature-dependent behavior
The temperature offset gradients for both channels depend on the value at 25°C. The gradients can be calculated
using the following linear equations:
O
The application note “TLE5011 Calibration” describes in chapter 2.3, how to determine the coefficients (KT
KT
Orthogonality Definition
The corresponding maximum and zero-crossing points of the SIN and COS signals do not occur at the precise
distance of 90°. The difference between X and Y phase is called the orthogonality error.
