MLX90825GXP-DAD-504-SP

Pressure Sensors Transducers Overview

The MLX90825GXP-DAD-504-SP is a PCB-less relative MEMS pressure sensor IC from Melexis, featuring a UART interface and no NTC. It measures differential pressure ranging from -0.3 to 1.0 bar (-30 kPa to 100 kPa). The device provides a 12-bit digital output in a 4-SIP module package. It operates within an extended temperature range of -40°C to 160°C and maintains up to 0.5% full-scale accuracy over its lifespan. The component is AEC-Q100 qualified and ASIL B compliant for safety-critical automotive applications.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix DAD-504-SP against official Melexis documentation to confirm the UART interface and absence of NTC thermistor. Ensure the -0.3 to 1.0 bar relative pressure range matches the target application requirements. Confirm that the 4-SIP module package format is compatible with the intended PCB layout and assembly processes. Cross-reference the AEC-Q100 qualification status for automotive reliability standards.

Pressure Sensors Transducers Selection Notes

Select this component when a compact, PCB-less solution is required for relative pressure sensing in harsh automotive environments. The lack of an integrated NTC distinguishes it from variants offering temperature compensation inputs. Consider the UART interface for simpler communication needs compared to SENT protocols. Validate that the 12-bit resolution and 0.5% FS accuracy meet the system's precision requirements.

Pressure Sensors Transducers Part Context

This part belongs to the MLX90825 series of PCB-less relative pressure sensors. It shares the core MEMS technology and ASIL B compliance with other variants in the family. Differences lie in pressure spans, interfaces (UART vs. SENT), and NTC availability. The GXP-DAD-504-SP designation specifies the particular pressure range and communication protocol configuration.
