General Description
The MLX90809 is a packaged, factory calibrated, integrated relative pressure sensor delivering a ratiometric analog or digital (using the SENT protocol) signal.
Use of an optimized architecture and a high density CMOS technology imparts the MLX90809 with best in class automotive EMC performance. A DSP based architecture using a 16bit microcontroller provides outstanding performance.
A smart package and die assembly concept suits applications with stringent automotive temperature and stress conditions needing small drift over life.
