• Manufacturer Part Number: mlx90333
• Description: Triaxis? 3d-joystick Position Sensor
• Manufacturer: Melexis Company

For instance, the analog output can be programmed for offset, gain and clamping to meet any rotary
position sensor output transfer characteristic:
where Voffset, Gain, ClampLo and ClampHi are the main adjustable parameters for the end-user.
The linear part of the transfer curve can be adjusted through a 3 point calibration. Once only one output is
used, a 5 point calibration is also available for further improvement of the linearity.
The calibration parameters are stored in EEPROM featuring a Hamming Error Correction Coding (ECC).
The programming steps do not require any dedicated pins. The operation is done using the supply and
output nodes of the IC. The programming of the MLX90333 is handled at both engineering lab and
production line levels by the Melexis Programming Unit PTC-04 with the MLX90316 daughterboard and
dedicated software tools (DLL − User Interface).

Vout(α) = ClampLo
Vout(α) = Voffset + Gain × α
Vout(α) = ClampHi
Vout(β) = ClampLo
Vout(β) = Voffset + Gain × β
Vout(β) = ClampHi
