General Description
The MLX90818 is a packaged, factory calibrated, absolute pressure sensor delivering a digital output signal using the SENT protocol.
Use of an optimized architecture and a high density CMOS technology imparts the MLX90818 with best in class automotive EMC performance. A DSP based architecture using a 16bit microcontroller provides outstanding performance in terms of initial accuracy.
A smart package and die assembly concept suits applications with stringent automotive temperature and stress conditions needing small drift over life.
