MLX90825GXP-DAD-400-RE

Pressure Sensors Transducers Overview

The MLX90825GXP-DAD-400-RE is a PCB-less relative MEMS pressure sensor IC from Melexis, featuring a SENT digital output. It measures relative pressure spans from -0.2 to 0.8 bar (20kPa to 80kPa). The device delivers an output range of 193 to 3896 LSB. It does not include an integrated NTC thermistor. Designed for automotive applications, it maintains ±0.5% full-scale accuracy over its lifespan and operates within a temperature range of -40°C to 160°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'DAD-400-RE' against official Melexis documentation to confirm the exact pressure span (-0.2 to 0.8 bar), SENT output protocol, and absence of NTC. Ensure compatibility with board-mount assembly processes. Cross-reference part numbers carefully as minor suffix variations indicate different pressure ranges or communication interfaces.

Pressure Sensors Transducers Selection Notes

Select this component when a robust, PCB-less relative pressure sensor with SENT output is required for automotive environments. It is suitable for applications demanding ASIL B compliance and long-term stability without external calibration. Consider alternatives if an integrated NTC or different pressure range is needed.
