Once the position (angular or linear stroke) information is computed, it is further conditioned (mapped) vs.

the target transfer characteristic and it is provided at the output(s) as SENT output.

The linear part of the transfer curve can be adjusted through a multi-point calibration:

This back-end step consists of a Piece-Wise-Linear (PWL) output transfer characteristic - 17 equidistant

points with programmable origin over 16 different angle ranges from 65 to 360 degrees.

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 MLX90366 is handled at both engineering lab and

production line levels by the Melexis Programming Unit PTC-04 with the daughterboard DB90316 +

dedicated MLX90367 software.
