The MLX90816 can also be used with full scale pressures other than 50bar (30 to 50bar). Contact Melexis for
detailed information on the IC performance at different full scale pressures.
10. Application Information
The MLX90816 is a very reliable discrete absolute pressure sensor fully automotive qualified. Like all Melexis
pressure sensors it has been qualified beyond typical semiconductors qualification standards. For harsh
media applications the MLX90816 can be used in a fluid filled housing.
If the application requires an amplified conditioned output the MLX90816 can be used in combination with
Melexis sensor interfaces IC like the MLX90328 and the MLX90329. By programming some calibration
settings in the sensor interface IC the sensitivity and offset variations from part to part as well as their
variations over temperature can be compensated for.
