MLX90809

Relative Pressure Sensor

8 Programmed Settings

The MLX90809 is calibrated at the final manufacturing test step. During the calibration, settings are stored in

the on chip (16x32bit) EEPROM to define the pressure transfer curve as well as the output clamping levels.

Together with the transfer functions, the IC filter values are set. The default programmed filter settings lead to

the noise level and response times described in paragraph 6. The transfer functions calibrated in the different

MLX90809LXG-EAD-xxx products with its corresponding performance level maintained over the full

temperature range and over life is described for each specific option code below.

The MLX90809 can be programmed for pressure spans like those described in paragraph 6 with the

atmospheric pressure always inside of the application range.

Contact Melexis for information on the expected accuracy for other ranges or transfer functions than the

default programmed ones.

Melexis can support customers delivering parts calibrated with other settings or can support customers by

delivering the necessary programming hardware, software and documentation to be able to program the

transfer function on the customers manufacturing line. To learn how to use the Melexis hardware and

software to program the MLX90809 read the application note “MLX90809 PTC04 Software Description”.
