Product details
Overview
MLX90809LXG-EAD-000-SP from Melexis is a factory-calibrated, integrated relative pressure sensor delivering ratiometric analog output (0.5–4.5 V) over a 0.05 to –1.05 bar pressure range, with ±1.5% FSO accuracy, automotive-grade temperature operation (–40°C to 150°C), and built-in SENT/diagnostic capability. It serves as a direct-mount pressure transducer in vacuum-sensing systems such as clogged filter detection and seat lumbar control.
For engineers reviewing the MLX90809LXG-EAD-000-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, calibrated transfer function details, diagnostic configuration options, package mechanical data, and real-world automotive and industrial use cases - all grounded in Melexis Revision 005 documentation.
Technical Context
The MLX90809LXG-EAD-000-SP integrates a piezoresistive MEMS sensing element, 16-bit microcontroller-based DSP, analog front-end with gain/offset compensation, and dual-output architecture supporting either analog (12-bit DAC-driven) or SENT (SAE J2716-compliant) signaling. Its backside-exposed diaphragm enables direct media contact with high resistance to automotive fluids.
It features programmable clamping (LCL = 0.49–0.51 V, HCL = 4.49–4.51 V), broken-wire diagnostics, overvoltage/reverse-voltage protection (–14 V at 150°C), and internal temperature compensation validated across –40°C to 150°C. The default filter settings yield 1 ms analog response time and ≤2 mVrms output noise (BW = 50 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0.05 to –1.05 bar relative: enables precise vacuum measurement for filter monitoring and cabin pressure control. |
| Output Type | Ratiometric analog (0.5–4.5 V): scales linearly with supply voltage (4.5–5.5 V), simplifying ADC reference alignment. |
| Accuracy | ±1.5% FSO: includes drift over temperature and lifetime, validated per AEC-Q100 for automotive reliability. |
| Operating Temp | –40°C to 150°C: supports under-hood and transmission-mounted applications without external thermal shielding. |
| Supply Current | 7–8 mA at 5 V: enables low-power operation in always-on vehicle subsystems like HVAC or brake assist. |
| Response Time | 1 ms (analog), 3–4 SENT frames: meets real-time vacuum leak detection and dynamic load-sensing requirements. |
| Burst Pressure | 5 bar at room temperature: provides robust mechanical margin against transient overpressure events. |
Pinout & Package
MLX90809LXG-EAD-000-SP uses a 16-pin SOIC-16W package (body: 10.33 × 7.59 × 2.45 mm, standoff: 0.075 mm) with backside pressure port and top-side marking. Only one of each functional pin group must be connected: Supply Input (pins 3 or 14), Ground (pins 6 or 11), Analog Output (pins 7–10), or SENT Output (pins 1–2, 15–16). Test pins (4, 13) and NC pins (5, 12) are unused in standard operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | SENT Output | Differential SENT signal driver compliant with SAE J2716; only one required for interface. |
| 3, 14 | Supply Input | 5 V nominal input with overvoltage protection up to +18 V and reverse protection to –14 V. |
| 6, 11 | Ground | Reference return path; broken-wire detection triggers diagnostic state if disconnected. |
| 7–10 | Analog Output | Ratiometric 0.5–4.5 V output; load capacitance limited to 470 nF, resistive load ≥4.7 kΩ. |
| 4, 13 | Test Pin | Factory test access; recommended to tie to GND when using analog output mode. |
Key Features
| Feature | Design Value |
|---|---|
| Backside-exposed MEMS diaphragm | Enables direct mounting to vacuum lines or fluid chambers without external ports or gaskets. |
| Programmable clamping levels | LCL = 0.49–0.51 V / HCL = 4.49–4.51 V: prevents signal saturation during transient over/under-pressure events. |
| Integrated diagnostics | Broken-track, overvoltage, under-voltage, overpressure, and under-pressure detection via EEPROM-configurable logic. |
| Factory-calibrated transfer curve | Pre-programmed 0.05 to –1.05 bar → 0.5 to 4.5 V mapping with ±16.5 mBar pressure accuracy over life and temperature. |
| Automotive EMC resilience | Optimized CMOS layout and on-chip regulators deliver best-in-class immunity per ISO 11452 and CISPR 25. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar relative pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90809LXG-EAD-003 | 0 to +1 bar range, same analog output (0.5–4.5 V), identical package and pinout. | Designed for positive-pressure applications (e.g., turbo boost, fuel rail), not vacuum. | Select EAD-003 only when measuring above-atmospheric pressure; EAD-000 remains optimal for vacuum-centric designs. |
| MPX5700AP | Analog-only (0–5 V), no SENT or diagnostics; ±2% FSO accuracy; operates to 125°C only. | Lacks automotive diagnostics, programmable clamping, and extended temperature range. | MPX5700AP suits cost-sensitive non-automotive industrial vacuum monitoring where diagnostics and 150°C operation are unnecessary. |
Compared with MLX90809LXG-EAD-000-SP, EAD-003 shifts full-scale range to positive pressure without changing interface or reliability, while MPX5700AP sacrifices diagnostics, temperature range, and accuracy for lower BOM cost in less demanding environments.

FAQ
What pressure range does the MLX90809LXG-EAD-000-SP support?
The MLX90809LXG-EAD-000-SP is calibrated for a relative pressure range of 0.05 to –1.05 bar, optimized for vacuum measurement applications such as clogged filter detection and seat lumbar cushion control. This range ensures full 4 V analog output span (0.5–4.5 V) with ±16.5 mBar pressure accuracy over temperature and lifetime, as specified in Melexis Revision 005 documentation.
Does the MLX90809LXG-EAD-000-SP support both analog and digital output simultaneously?
No - the MLX90809LXG-EAD-000-SP supports either ratiometric analog output (pins 7–10) or SENT digital output (pins 1, 2, 15, 16), but not both concurrently. External circuitry must isolate the unused output type: Melexis recommends grounding one SENT pin and the test pin (4 or 13) when using analog mode, and grounding one analog pin plus the test pin when using SENT mode.
What diagnostic capabilities are built into the MLX90809LXG-EAD-000-SP?
The MLX90809LXG-EAD-000-SP includes broken-wire detection, overvoltage/under-voltage monitoring, overpressure/under-pressure alarms, and programmable clamping (LCL/HCL). These diagnostics are configurable via on-chip EEPROM and reported through SENT frames or analog output saturation, enabling fail-safe behavior in ASIL-B–compatible systems without external supervision.
Is the MLX90809LXG-EAD-000-SP qualified for automotive use?
Yes - the MLX90809LXG-EAD-000-SP is AEC-Q100 qualified, operates from –40°C to 150°C, and includes automotive-specific features including EMC-hardened design, reverse-voltage protection (–14 V at 150°C), burst pressure rating (5 bar), and diagnostic functions aligned with ISO 26262 requirements for functional safety.
Can the MLX90809LXG-EAD-000-SP be reprogrammed in-system?
Yes - the MLX90809LXG-EAD-000-SP contains 16×32-bit EEPROM that stores calibration coefficients, clamping levels, and filter settings. Melexis provides PTC04 programming hardware and software to enable in-line reprogramming of transfer functions, allowing customization for non-standard pressure ranges or updated diagnostics without changing the MLX90809LXG-EAD-000-SP hardware.
