Triaxis® Position Sensor IC
14.2.5. 17-Pts LNR Parameters
The LNR parameters, together with the clamping values, fully define the relation (the transfer function)
between the digital angle and the output signal.
The shape of the MLX90365 transfer function from the digital angle value to the output voltage is
described by the drawing below. In the 16-Pts mode, the output transfer characteristic is Piece-Wise-
Linear (PWL).
Figure 10 - Input range from 65.5°up to 360°
All the Y-coordinates can be programmed from -50% up to +150% to allow clamping in the middle of one
segment (like on the figure), but the output value is limited to CLAMPLOW and CLAMPHIGH values.
Between two consecutive points, the output characteristic is interpolated.
The parameter W determines the input range on which the 17 points (16 segments) are uniformly spread:
