6.3

Behavior of Sensor Outputs

Following graphs show the behavior at different output settings over one mechanical 360° rotation.

6.3.1

Differential Output Mode (Default Setting)

Positive SINP and COSP signals in combination with inverted SINN and COSN are provided via the

output pins of the sensor. High immunity against common cause errors, evoked by the environment of

the sensor, is given due to the differential signal transmission. Fully differential signal inputs are

required to digitize the analog outputs. VCM is defined via OTP programming.

6.3.2

Single-Ended Output Mode

Positive SINP and COSP signals in combination with the configured VCM level on CM_SIN and

CM_COS are provided via the output pins of the sensor. To achieve best accuracy performance, fully

differential signal inputs are recommended to digitize the analog outputs. As an alternative, single-

ended measurement of all output signals with associated data processing (SINP - CM_SIN, COSP -

CM_COS) is as well possible.
