MLX90822GXP-BAB-305-RE

Pressure Sensors Transducers Overview

The MLX90822GXP-BAB-305-RE is a packaged, PCB-less absolute pressure sensor IC from Melexis Technologies NV. It measures an absolute pressure range of 0.1 to 3.5 bar and provides an analog voltage output signal ranging from 0.5V to 4.5V. The device integrates a MEMS pressure sensing element with a CMOS interface chip and passive components. It is factory calibrated and designed for high EMC performance. The component operates within a temperature range of -40°C to 160°C and maintains an accuracy of +/-0.5% full scale over its lifespan.

Pressure Sensors Transducers Feature Summary

• PCB-less packaging design ensures measurement accuracy remains unaffected by sensor integration processes.
• Factory calibration combined with DSP-based signal interface delivers outstanding initial accuracy.
• Smart package and die assembly concept enables high output stability throughout the operational lifespan under stringent automotive conditions.

Pressure Sensors Transducers Applications

• Fuel vapor pressure measurement
• Crankcase ventilation monitoring
• Exhaust gas recirculation (EGR) systems

Pressure Sensors Transducers Procurement Notes

Verify that the specific suffix '305' corresponds to the required 0.1 to 3.5 bar pressure span and 0.5V to 4.5V analog output range. Confirm compatibility with ASIL A safety requirements if applicable to the target system. Ensure the reel packaging format meets production line handling specifications. Cross-reference the datasheet for precise mechanical dimensions and thermal characteristics before finalizing the bill of materials.

Pressure Sensors Transducers Selection Notes

Select this model when an analog voltage output is preferred over digital protocols like SENT. The PCB-less form factor is critical for applications where board-level integration errors must be eliminated. Consider the operating temperature range and long-term stability requirements. Verify that the 3.5 bar maximum pressure limit aligns with the system's peak pressure constraints without requiring additional derating margins.

Pressure Sensors Transducers Part Context

This component belongs to the MLX90822 series of absolute pressure sensors. It shares the same core MEMS technology and PCB-less architecture as other variants in the family but differs in pressure span and output configuration. The series is designed for automotive applications requiring high reliability and precision under harsh environmental conditions.

Pressure Sensors Transducers Replacement Considerations

MLX90822GXP-BAB-302-RE is a variant with a different pressure span (0.1 to 4 bar). Substitution requires verification that the new pressure range fits the application limits and that the analog output characteristics remain compatible with the host circuitry.
