MLX90821LXG-DBA-003-RE

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-003-RE is a factory-calibrated, packaged relative pressure sensor from Melexis. It delivers a ratiometric analog output or SENT digital signal. The device measures differential pressure within a range of -6 kPa to 26 kPa (-0.87 PSI to 3.77 PSI). The analog output voltage spans from 0.5 V to 4.5 V. It operates on a supply voltage between 4.5 V and 5.5 V. The component features a 16-bit resolution and is housed in a 16-SOIC package with an exposed pad. It supports surface mount installation and functions within a temperature range of -40°C to +150°C.

Pressure Sensors Transducers Feature Summary

• Factory calibration ensures high accuracy without external adjustment.
• Offers dual output options including ratiometric analog voltage and SENT digital protocol.
• Integrated temperature compensation for stable performance across wide thermal ranges.
• Packaged design provides robust protection for board-mounted applications.

Pressure Sensors Transducers Applications

• Board mount pressure sensing systems
• Differential pressure measurement in industrial environments
• Automotive pneumatic system monitoring

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix code to confirm the exact pressure range and output type, as variations exist within the MLX90821 family. Ensure compatibility with the 16-SOIC footprint and exposed pad thermal requirements during PCB layout. Confirm that the selected variant meets the required operating temperature range and supply voltage specifications for the target application environment before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this model when a factory-calibrated relative pressure sensor with either analog or SENT output is required. The -003-RE suffix indicates a specific pressure range of -6 kPa to 26 kPa. Consider the 16-SOIC package size and exposed pad for thermal management if high power dissipation is expected. Ensure the application does not require absolute pressure measurement, as this is a relative/differential sensor.
