MLX90821LXG-DBA-007-RE

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-007-RE is a factory-calibrated integrated relative pressure sensor from Melexis, designed for automotive applications. It features a differential operating pressure range of -10 kPa to +10 kPa (-1.45 PSI to +1.45 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 an operating current of 8.5 mA. Accuracy is specified at ±2.5%. The sensor is housed in a 16-SOIC package (7.50 mm width) with exposed pads, supporting surface mount installation across a temperature range of -40°C to +150°C.

Pressure Sensors Transducers Feature Summary

• Delivers a ratiometric analog output signal proportional to the supply voltage for direct interface with standard microcontrollers.
• Includes factory calibration and temperature compensation to ensure high accuracy across the full automotive operating temperature range.
• Features a robust back-pressure package design that offers high compatibility with various automotive media and facilitates easy sealing.
• Supports board-mount installation in a compact 16-SOIC form factor suitable for space-constrained electronic control units.

Pressure Sensors Transducers Applications

• Fuel vapor pressure measurement in evaporative emission control systems
• Low-pressure differential monitoring in intake manifolds
• Cabin air pressure sensing for climate control systems

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix '007' corresponds to the required -10 kPa to +10 kPa pressure range before ordering. Confirm the 16-SOIC package dimensions match the PCB footprint requirements. Check for moisture sensitivity level (MSL 3) handling instructions during assembly. Ensure the analog output configuration meets the input voltage thresholds of the target microcontroller ADC.

Pressure Sensors Transducers Selection Notes

Select this model when a ratiometric analog output is preferred over digital SENT interfaces. The -10 kPa to +10 kPa range is optimal for ultra-low differential pressure measurements. Consider the 8.5 mA operating current for power budget calculations. The exposed pad design requires careful thermal management and soldering process optimization to ensure reliable joint formation.

Pressure Sensors Transducers Part Context

This component belongs to the MLX90821 series of ultra-low relative pressure sensors designed for harsh automotive environments. The series includes variants with different pressure ranges and output types, such as SENT digital outputs. The MLX90821 family is characterized by its ability to measure low pressures with high precision while maintaining robustness against mechanical stress and chemical exposure common in vehicle under-hood applications.

Pressure Sensors Transducers Replacement Considerations

Direct functional substitutes within the same package and pinout must be verified via official cross-reference lists. Variants like MLX90821LXG-DBA-005-RE offer different pressure ranges (-50 mbar to +50 mbar) but share similar electrical characteristics. Ensure any replacement maintains the 16-SOIC footprint and analog output polarity.
