Melexis MLX90822 Absolute Pressure Sensors

Melexis MLX90822 Absolute Pressure Sensors measure pressure spans from 1 to 4 bars and deliver an analog output signal. These sensors consist of a MEMS pressure sensor element, an interface chip with CMOS technology, and passive components. MLX90822 sensors exhibit excellent EMC performance, while the DSP-based signal interface provides high initial accuracy. The efficient package and die assembly concept enables high output stability over life, even in stringent automotive stress and temperature conditions. Melexis MLX90822 Absolute Pressure Sensors are suitable for combustion-powered applications, including boats, mowers, and chainsaws.
