MLX90821LXG-DBA-003-SP

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-003-SP is a factory-calibrated, packaged relative pressure sensor from Melexis Technologies NV. It measures differential pressure within a range of -6 kPa to 26 kPa (-0.87 PSI to 3.77 PSI). The device provides a ratiometric analog output voltage spanning 0.5 V to 4.5 V. It operates on a supply voltage between 4.5 V and 5.5 V with a typical current consumption of 8.5 mA. The sensor features 16-bit resolution and is housed in a 16-SOIC package (0.295 inch width) designed for surface mount installation.

Pressure Sensors Transducers Feature Summary

• Delivers a ratiometric analog output signal proportional to the supply voltage
• Factory calibrated for high accuracy across the automotive temperature range
• Integrated NTC thermistor enables precise medium temperature measurement
• Robust packaging design ensures compatibility with common automotive media

Pressure Sensors Transducers Applications

• Automotive fuel vapor pressure monitoring systems
• Engine intake manifold absolute pressure sensing
• Turbocharger boost pressure measurement
• EGR system flow control applications

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix code matches the required pressure range and output type before ordering. Confirm that the 16-SOIC package dimensions align with the target PCB footprint. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer datasheet for latest revision status and compliance documentation.

Pressure Sensors Transducers Selection Notes

Select this component when a wide differential pressure range up to 26 kPa is required alongside analog interface simplicity. The ratiometric output simplifies ADC interfacing by canceling out supply voltage variations. Consider the integrated temperature compensation if ambient or medium temperature data is needed without additional sensors.

Pressure Sensors Transducers Part Context

This part belongs to the MLX90821 series of ultra-low pressure relative pressure sensors designed for automotive applications. The series offers both analog and SENT digital outputs. The DBA variant specifically denotes the differential pressure configuration with analog output, distinguishing it from other pressure ranges or digital-only variants in the family.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes include other MLX90821 variants with identical pressure ranges and analog outputs, such as MLX90821LXG-DBA-003-RE. Verify pinout compatibility and thermal characteristics when replacing components from different manufacturers.
