The MLX90257 is an integrated relative pressure sensor (2 pressure ports) realized in a standard 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.
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 10 Bar full scale ranges).
