Product description

The MLX90820 is a fully integrated absolute pressure sensor for mid-pressure range (10 - 50 bar) applications, with a configurable output in either digital (SENT) or analog (ratiometric to the supply) signal.

Its complete level of integration (MEMS, front-end, back-end, microcontroller) allows not only system miniaturization but also the simplification of its assembly process. And the output flexibility supports legacy application as well as new trends.

The MLX90820 is the ideal bare die solution for pressure sensor applications requiring high accuracy, high EMC robustness and miniaturization.

The product has been designed to achieve an outstanding robustness in oil-filled modules.

The use of an optimized architecture and a high density CMOS technology imparts the MLX90820 with best in class automotive EMC performance. A DSP based architecture using a 16-bit microcontroller provides exceptional performance in terms of initial accuracy.
