The MLX90821 is a packaged, factory calibrated, relative pressure sensor delivering a ratiometric analog output or a digital signal using the SENT protocol.
Amongst others, the sensor measures fuel vapor pressure between 50 and 700 mbar and is certified for operation from -40 to +150 °C.
Using a best in class MEMS sensor enables reliably and accurately measuring very low pressures of a few tenths of millibars.
An optimized architecture and a high density CMOS technology imparts the MLX90821 with best in class automotive EMC performance.
A DSP based architecture using a 16bit microcontroller provides outstanding performance in terms of initial accuracy of both pressure and optionally external NTC temperature.
A smart package and die assembly concept suits applications with stringent automotive temperature and stress conditions needing small drift over life.
