MLX90821LXG-DBA-007-SP

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-007-SP is a factory-calibrated integrated relative pressure sensor designed for automotive applications. It features a differential pressure range of -0.4 to 0.4 bar and delivers a ratiometric analog output spanning 0.5 V to 4.5 V. The device operates on a supply voltage between 4.5 V and 5.5 V, with a typical current consumption of 8.5 mA. It provides 16-bit resolution and maintains an accuracy of 2.5%. The sensor functions within a temperature range of -40°C to +150°C and is housed in a 16-SOIC package.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'SP' against official Melexis documentation to confirm it denotes a standard sample or special configuration rather than a production reel variant. Ensure the ordering part number matches the required pressure range and output type exactly. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this component when a ratiometric analog interface is required for ultra-low differential pressure measurements in automotive environments. The 16-SOIC package offers a board-mount solution suitable for automated assembly. Consider the 2.5% accuracy and 16-bit resolution for applications demanding precise relative pressure data without digital SENT complexity.

Pressure Sensors Transducers Part Context

This part belongs to the MLX90821 series of ultra-low relative pressure sensors from Melexis. The series is engineered for automotive use, offering both analog and SENT digital outputs. The MLX90821 family addresses the need for robust, calibrated sensors in tight spaces, providing high immunity to electromagnetic interference and reliable operation under extreme thermal conditions common in modern vehicle powertrains.

Pressure Sensors Transducers Replacement Considerations

Consult official Melexis substitution lists for direct replacements. Generic pressure sensors may not match the factory calibration curves or ratiometric behavior. Verify pinout compatibility and package dimensions if considering alternative suppliers.
