Application Information

Several wiring options and configurations of AS5116 are possible. The most likely used options are

shown in the following section.

9.1

Differential Mode

By default, the configuration of the sensor is in differential output mode. Positive SINP and COSP

signals, as well as the inverted SINN and COSN signals are provided.

This is the recommended output configuration, due to the best common mode rejection. Fully

differential inputs are required on controller side. To improve the angle accuracy, a one-time end of

line calibration of offset and gain error is recommended before calculating the angle position.
