Overview

The MLX90809LXG-EAD-000-SP is a factory-calibrated, automotive-qualified differential pressure sensor designed to measure relative pressures between -105kPa and 5kPa. It integrates a MEMS sensor element with a 16-bit microcontroller, analog front-end, and DSP circuitry to provide a temperature-compensated 0.5 V to 4.5 V analog output.

Why Choose This Part

This sensor offers high integration by combining the MEMS sensing element with a 16-bit MCU for internal signal processing, resulting in an accuracy of +/-1.5%. Its AEC-Q100 qualification and built-in diagnostic features make it highly reliable for harsh automotive and industrial environments.

Applications

Automotive Diesel Particulate Filter Monitoring
Utilizes the differential pressure range to monitor exhaust backpressure and filter loading in passenger vehicles.
Crankcase Ventilation Systems
Monitors blow-by gas pressure to ensure engine efficiency and compliance with emission standards.
HVAC Airflow Management
Measures small pressure drops across filters or heat exchangers in industrial climate control systems.
Industrial Process Control
Provides precise relative pressure monitoring for low-pressure gas lines and pneumatic equipment.

Getting Started

Integration requires connecting the 4.5V to 5.5V supply and routing the analog output to a high-impedance ADC input. While factory calibrated for analog output, the device also supports the SENT protocol for digital communication and includes 128 bytes of EEPROM for storing application-specific configuration data.
