General Description
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).
