Electrical parameters

The indicated electrical parameters apply to the full operating range, unless otherwise specified. The typical

values correspond to the specified supply voltage range and 25°C, unless individually specified. All other

2.3.3

Output parameters

All parameters apply over the full operating range, unless otherwise specified. The parameters in Table 6 refer

to single pin output and Table 7 to differential output. For variable names please refer to Figure 15 “GMR

sensor single-ended output signals” on Page 18 and Figure 17 “GMR differential output of ideal cosine” on

Page 19.

The following equations describe various types of errors that combine to the overall angle error.

The maximum and zero-crossing of the SIN and COS signals do not occur at the precise angle of 90°. The

difference between the X and Y phases is called the orthogonality error. In Equation (3) the angle at zero

crossing of the X COS output is subtracted from the angle at the maximum of the Y SIN output, which describes

the orthogonality of X and Y.

(3)

The amplitudes of SIN and COS signals are not equal to each other. The amplitude mismatch is defined as

synchronism, shown in Equation (4). This value could also be described as amplitude ratio mismatch.
