MLX90821LXG-DBA-008-RE

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-008-RE is a factory-calibrated integrated relative pressure sensor designed for automotive applications. It delivers an analog voltage output ranging from 0.5V to 4.5V, corresponding to a differential pressure range of -3.72kPa to 1.24kPa (-0.54PSI to 0.18PSI). The device operates on a supply voltage between 4.5V and 5.5V, with a typical current consumption of 8.5mA. It features a 16-bit resolution and maintains an accuracy of ±0.03PSI (±0.2kPa). Packaged in a 16-SOIC surface-mount format with exposed pads, it supports operation across a wide temperature range from -40°C to +150°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix configuration against the official Melexis datasheet to ensure correct pressure range and output type compatibility. Confirm that the 16-SOIC package dimensions align with the target PCB footprint. Check RoHS compliance status and moisture sensitivity level requirements for the assembly process. Ensure the application environment stays within the specified -40°C to +150°C operating temperature limits.

Pressure Sensors Transducers Selection Notes

Select this component when a low-range differential pressure measurement is required with an analog interface. The 0.5V to 4.5V output allows direct interfacing with standard ADCs without additional scaling circuitry. Consider the exposed pad thermal design for optimal heat dissipation during operation. Verify that the ±0.03PSI accuracy meets the system's error budget constraints.
