2. Description

The MLX90269 is an integrated

absolute pressure sensor (0 Bar

= vacuum) realized in CMOS

OUT 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).
