Pressure Sensors Transducers Procurement Notes

Verify the specific suffix DAD-301-RE against official Melexis documentation to confirm the exact pressure range and calibration curve. Ensure compatibility with SENT interface requirements in the target system. Check for AEC-Q100 qualification status if automotive deployment is intended. Confirm package type matches the SIP-4 specification. Validate operating temperature limits against environmental conditions.

Pressure Sensors Transducers Selection Notes

Select this model when a digital SENT interface is required for absolute pressure measurement up to 300 kPa. The integrated NTC simplifies thermal compensation compared to external solutions. Consider the ASIL B rating for functional safety requirements. Evaluate the wide operating temperature range for harsh environments. Compare with other MLX90824 variants for different pressure ranges or output types.
