Product Description
Product Overview
The MLX90822 is a packaged, PCB-less, factory-calibrated absolute pressure sensor designed for automotive applications. It measures pressure spans from 1 to 4 bar and provides a ratiometric analog output. The sensor integrates a MEMS pressure element, an interface chip, and passive components into a single, easy-to-integrate package, offering excellent EMC performance and high output stability over life, even under stringent automotive temperature and stress conditions. It is developed as an ASIL A SEooC.
