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:

X25, OY25: Offset values at 25°C in digits.

The application note “TLE5011 Calibration” describes in chapter 2.3, how to determine the coefficients (KT

OX,

OY).

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

ideal = 0°

X: Phase error of X (= cos) signal

Y: Phase error of Y (= sin) signal
