Product details
Overview
MLX90809LXG-EAD-003-SP from Melexis is a factory-calibrated, integrated relative pressure sensor delivering ratiometric analog output (0.5–4.5 V) over 0–1 bar pressure range, with ±1.5%FSO overall accuracy, automotive-grade temperature operation (−40°C to +150°C), and built-in diagnostics for vacuum measurement in engine intake manifolds.
For engineers reviewing the MLX90809LXG-EAD-003-SP datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package dimensions, SENT/analog mode configuration guidance, diagnostic thresholds, and calibrated transfer function details specific to the EAD-003 variant.
Technical Context
The MLX90809LXG-EAD-003-SP integrates a piezoresistive MEMS sensing element, 16-bit microcontroller-based DSP, 12-bit DAC, analog front-end, and SENT protocol driver in a single IC. Its architecture enables real-time gain/offset compensation across temperature and programmable pressure linearization.
It supports dual-output modes: analog (ratiometric, 0.5–4.5 V) and SENT (SAE J2716 compliant), with configurable clamping levels (0.49–0.51 V low / 4.49–4.51 V high), broken-wire detection, and overvoltage/reverse-voltage protection up to 18 V and −14 V respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 1 bar relative (positive pressure on package top side); atmospheric pressure lies within span. |
| Analog Output | 0.5–4.5 V ratiometric output; 4 V span directly maps full pressure range for stable ADC interfacing. |
| Overall Accuracy | ±1.5% FSO including drift over temperature (−40°C to +150°C) and lifetime; ±15 mBar pressure error. |
| Response Time | 1 ms (10%–90%) for analog output under default filter settings (SSF = 1, PFLT = 0). |
| Supply Voltage | 4.5–5.5 V nominal; survives 18 V overvoltage indefinitely and −14 V reverse voltage for 1 hour at 150°C. |
| Diagnostic Clamping | Programmable low/high clamping levels (±10 mV accuracy); default LCL = 0.5 V, HCL = 4.5 V. |
| Burst Pressure | 5 bar at room temperature per AEC-Q100-002; ensures mechanical robustness in high-stress environments. |
Pinout & Package
MLX90809LXG-EAD-003-SP uses a 16-pin SOIC-16 package (body size 10.33 × 7.59 × 2.45 mm, stand-off 0.075 mm) with backside-exposed pressure port. Only three pins require connection: one Supply Input (Pin 3 or 14), one Ground (Pin 6 or 11), and one Analog Output (Pin 7, 8, 9, or 10). SENT pins (1, 2, 15, 16) and Test pins (4, 13) are unused in analog mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | SENT Output | Unused in analog mode; must be left floating or tied to GND per design guidelines. |
| 3, 14 | Supply Input (VDD) | Primary power input; either pin may be used - no internal connection between them. |
| 4, 13 | Test Pin | Unused in production; recommended to tie to GND when using analog output. |
| 5, 12 | Not Connected | No internal connection; must remain unconnected. |
| 6, 11 | Ground (GND) | Reference return path; either pin may be used - no internal connection between them. |
| 7, 8, 9, 10 | Analog Output (VOUT) | Ratiometric 0.5–4.5 V output; only one required; load capacitance ≤470 nF, resistance ≥4.7 kΩ. |
Key Features
| Feature | Design Value |
|---|---|
| Backside-exposed MEMS diaphragm | Enables direct media contact with automotive fluids/vacuum; higher resistance to oil, coolant, and brake fluid than front-side sensors. |
| Factory-calibrated transfer curve | Pre-programmed 0–1 bar → 0.5–4.5 V mapping stored in EEPROM; eliminates field calibration for intake manifold vacuum monitoring. |
| Integrated diagnostics | Detects open-circuit supply/ground (broken wire), overpressure, undervoltage, and clamping violations - all reportable via analog rail states. |
| Automotive EMC resilience | Optimized CMOS layout and on-chip regulators deliver best-in-class immunity per ISO 11452 and ISO 7637 without external filtering. |
| Robust sealing interface | Package designed for easy O-ring or epoxy seal against housing; pressure port located on backside for simplified mechanical integration. |
Applications
| Engine Intake Manifold Vacuum Sensing | Brake Booster Vacuum Monitoring |
|---|---|
|

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-000 | 0.05 to −1.05 bar range; negative-pressure optimized; same accuracy and package. | Designed for vacuum-only applications (e.g., turbocharger boost control); not suitable for positive-pressure use cases. | Select EAD-000 only when measuring vacuum below atmospheric pressure exclusively. |
| MLX90809LXG-EAD-007 | 0 to −1 bar range; inverted clamping (0.25–0.35 V low / 4.75–4.85 V high); same accuracy. | Targeted at vacuum-sensing with extended low-end resolution; clamping shifted to avoid noise near rails. | Choose EAD-007 for high-precision vacuum detection where 0.5 V rail proximity causes ADC quantization loss. |
Compared with MLX90809LXG-EAD-003-SP, EAD-000 supports deeper vacuum ranges but cannot measure positive pressure, while EAD-007 offers enhanced low-vacuum linearity at the cost of reduced headroom at 4.5 V - making EAD-003 the optimal choice for bidirectional 0–1 bar applications like intake manifold sensing.

FAQ
What pressure range does the MLX90809LXG-EAD-003-SP measure?
The MLX90809LXG-EAD-003-SP measures relative pressure from 0 to 1 bar (0–100 kPa) with the top side of the package exposed to ambient atmosphere and the backside port sensing applied pressure. Its transfer function is factory-programmed to output 0.5 V at 0 bar and 4.5 V at 1 bar, enabling direct interface with standard 12-bit automotive ADCs.
Does the MLX90809LXG-EAD-003-SP support SENT output?
No - the MLX90809LXG-EAD-003-SP is configured exclusively for ratiometric analog output (0.5–4.5 V). The SENT output capability is implemented only in the EAD-100 variant. Pins 1, 2, 15, and 16 on the MLX90809LXG-EAD-003-SP are reserved but inactive; Melexis recommends tying them to ground in analog-mode applications.
What is the operating temperature range of the MLX90809LXG-EAD-003-SP?
The MLX90809LXG-EAD-003-SP operates across −40°C to +150°C, fully qualified per AEC-Q100 Grade 0 requirements. All specifications - including ±1.5%FSO accuracy, 1 ms response time, and diagnostic thresholds - are guaranteed over this full range, making it suitable for under-hood engine bay placement.
How is the MLX90809LXG-EAD-003-SP calibrated?
The MLX90809LXG-EAD-003-SP undergoes final-test calibration at Melexis, with pressure transfer coefficients, clamping levels, and filter settings permanently stored in on-chip EEPROM. No field calibration is needed; the device ships ready for drop-in use in 0–1 bar analog pressure measurement systems.
What external components are required for the MLX90809LXG-EAD-003-SP?
Only two external capacitors are required: a 47 nF ceramic decoupling capacitor on the VDD line and a 47 nF load capacitor on the analog output pin. When using analog mode, Melexis further recommends shorting one Test pin (Pin 4 or 13) to ground to suppress noise coupling - no resistors or additional ICs are needed.
