Description
1.2 to 3 Bar Full Scale
1. Functional Diagram
2. Description
The MLX90269 is an integrated
absolute pressure sensor (0 Bar
= vacuum) realized in CMOS
technology with micromachining
options. It consists of an analog
signal chain that interacts with
the digital core and on-chip
temperature sensor in order to
provide uniform overall sensing
characteristics after calibration
and to cancel the temperature
related parameter drifts.

Diagnostics
The output is proportional to the
applied pressure with an adjustable slope and offset. It is ratiometric and goes rail-to-rail with a 3mA
source and sink capability. Different pressure ranges are available (from 1.2 to 7 Bar full scale ranges,
see above ordering information).
