• Manufacturer Part Number: MLX90316EDC
• Description: Rotary Position Sensor IC
• Manufacturer: ETC2 [List of Unclassifed Manufacturers]

14.2. Output Transfert Characteristic
14.2.1. CLOCKWISE Parameter
The CLOCKWISE parameter defines the magnet rotation direction.
Refer to the drawing in the IMC positioning sections (Section 19.3 and 19.6).
14.2.2. 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 90316 transfer function from the digital angle value to the output voltage is described by
the drawing below. Six segments can be programmed but the clamping levels are necessarily flat.
Two, three, or even five calibration points are then available, reducing the overall non-linearity of the IC by
almost an order of magnitude each time. Three or five point calibration will be preferred by customers
looking for excellent non-linearity figures. Two-point calibrations will be preferred by customers looking for
a cheaper calibration set-up and shorter calibration time.

CCW is the defined by the 1-4-5-8 pin order direction for the SOIC8 package and 1-8-9-16 pin
order direction for the TSSOP16 package.
CW is defined by the reverse direction: 8-5-4-1 pin order direction for the SOIC8 and 16-9-8-1 pin
order direction for the TSSOP16 package.
