Melexis MLX90823GXP-BAD-306-SP

The MLX90823 is a PCB-free, factory-calibrated relative pressure sensor capable of measuring pressure in the range of 0.1 bar to 1.5 bar, providing an analog output signal.

The MLX90823 consists of a MEMS pressure sensing element, an interface IC (CMOS technology), and passive components. This optimized solution delivers excellent EMC performance. The DSP-based signal interface provides outstanding initial accuracy. The intelligent packaging and die assembly concept ensures long-term high output stability even under harsh automotive temperature and stress conditions.
