Figure 4-1 Functional block diagram MLX90815
The MLX90815 discrete micromachined
absolute pressure sensors has been
designed for an optimal performance when
sensing pressures from 0 to 10..30 bar
absolute. This device is fully automotive
qualified. It can directly be used in non
corrosive/non aggressive media applications.
For harsh media, the MLX90815 can be used
in a fluid filled module design. The sensor is
a piezoresistive wheatstone bridge on a
membrane made with a silicon
micromachining process. As pressure is
applied on the membrane a differential
voltage change is seen across the
Wheatstone bridge outputs while a bias
voltage is applied to the bridge inputs.
The MLX90815 can be used in combination
with the Melexis sensor interfaces ICs that
can perform the conditioning of the bridge
signal
(MLX90328,
MLX90329).

The MLX90815 can also be used with full scale pressures other than 20bar (10 to 30bar). Contact Melexis for
detailed information on the IC performance at different full scale pressures.
10. Application Information
The MLX90815 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 MLX90815 can be used in a fluid filled housing.
If the application requires an amplified conditioned output the MLX90815 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.
