MLX90821LXG-DBA-005-RE

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-005-RE is a factory-calibrated integrated relative pressure sensor designed for automotive applications. It delivers a ratiometric analog output ranging from 0.5V to 4.5V, corresponding to a differential pressure range of -0.05 bar to 0.05 bar. The device features a 16-bit resolution and operates within a supply voltage window of 4.5V to 5.5V. It maintains an accuracy of 2.5% and functions reliably across a temperature range of -40°C to +150°C. Packaged in a SOIC-16 surface-mount format with a bare pad, it supports board mounting without external ports.

Pressure Sensors Transducers Feature Summary

• Delivers a ratiometric analog signal proportional to the supply voltage
• Factory calibrated for high precision relative pressure measurement
• Integrated NTC provides compensated medium temperature data
• Includes automotive-grade diagnostic functions such as clamp level and open circuit tracking

Pressure Sensors Transducers Applications

• Fuel vapor pressure monitoring systems
• Ultra-low pressure automotive media applications
• Extended experimental testing requiring robust low-pressure sensing

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix configuration against the official Melexis datasheet to ensure compatibility with required pressure ranges and output types. Confirm that the SOIC-16 package dimensions align with the target PCB footprint. Check export documentation requirements if sourcing from regions with restricted trade regulations. Ensure the operating environment stays within the specified -40°C to +150°C thermal limits for reliable performance.

Pressure Sensors Transducers Selection Notes

Select this component when a ratiometric analog interface is preferred over digital SENT outputs for ultra-low differential pressure measurements. The 0.5V to 4.5V output span allows direct interfacing with standard ADCs without additional scaling circuits. Consider the 16-bit resolution for applications demanding fine pressure discrimination. Verify that the no-port design fits the mechanical constraints of the intended assembly.

Pressure Sensors Transducers Part Context

This part belongs to the MLX90821 series of ultra-low relative pressure sensors tailored for automotive use. It shares the same core technology and packaging family as variants offering SENT digital outputs or different pressure ranges. The DBA suffix indicates specific calibration and output characteristics unique to this model. It complements other Melexis pressure solutions by providing a cost-effective analog option for non-critical diagnostic paths.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes include other MLX90821 variants with matching pressure ranges but different output protocols, such as SENT-enabled models. Cross-reference pinouts and thermal specifications before swapping. No alternative manufacturers offer identical integrated calibration and automotive diagnostics in this specific form factor.
