Product details
Overview
MLX90340EDC-AAA-000-RE from Melexis is a monolithic Triaxis® Hall-effect IC for absolute rotary and linear position sensing, delivering 12-bit analog or PWM output with programmable transfer characteristics, ±0.5° angular accuracy over -40°C to +85°C, and SOIC-8 packaging. It decodes Bx/By/Bz magnetic vector components to enable non-contacting potentiometer replacement in industrial motor feedback systems.
For engineers reviewing the MLX90340EDC-AAA-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, confirmed SOIC-8 pin functions, calibrated thermal accuracy data, and validated alternative options for heavy-duty position sensing designs.
Technical Context
The MLX90340EDC-AAA-000-RE integrates a tri-axis Hall front-end, 15-bit ADC, 16-bit RISC microcontroller with ROM firmware, and dual-output stage supporting ratiometric analog (12-bit DAC) or PWM (12-bit resolution). Its DSP computes magnetic angle via CoRDiC-based arctan(Bj/Bi) on two of three orthogonal flux components.
It features on-chip EEPROM with Hamming ECC for storing calibration parameters including 4-point or 17-point piecewise-linear transfer functions, gain/offset/clamp settings, and diagnostic thresholds-all programmable via VDD/OUT pins without dedicated programming interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Selectable ratiometric analog (0–VDD) or PWM (5–95% duty cycle); enables direct MCU ADC or timer capture interface without external signal conditioning. |
| Angular Resolution | 12-bit (4096 steps over full scale); supports sub-degree position discrimination in 360° rotary applications. |
| Thermal Accuracy | ±0.5° over -40°C to +85°C; achieved via intrinsic flux-density self-compensation and digital front-end compensation, reducing need for external temperature sensors. |
| Supply Voltage | 4.5–24 V; accommodates wide industrial rail ranges and reverse-voltage protection to -12 V prevents damage during battery polarity misconnection. |
| Transfer Calibration | Programmable 4-point LNR or 17-point PWL mapping; allows precise linearization across magnet placement tolerances and mechanical stroke nonlinearity. |
| Magnetic Range | ±1 T (±10 kG); compatible with standard NdFeB magnets at air gaps up to 5 mm, eliminating need for high-field rare-earth variants. |
| Diagnostic Capability | Programmable fixed-level diagnostics (e.g., open-circuit, short-to-rail, overtemperature); enables ASIL-B–compatible functional safety monitoring without external watchdog. |
Pinout & Package
MLX90340EDC-AAA-000-RE uses RoHS-compliant SOIC-8 package (5.3 mm × 6.2 mm, 1.27 mm pitch), optimized for surface-mount assembly and thermal dissipation in motor control enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – VDD | Power supply input | 4.5–24 V main supply; includes reverse-voltage protection and internal regulation for analog/digital domains. |
| 2 – Test Input | Factory test node | Used during wafer sort and final test; must be grounded per EMC recommendation if unused in system design. |
| 3 – Test | Factory test node | Internal logic access point; no user functionality; tie to GND for noise immunity. |
| 4 – Not Used | No internal connection | Unbonded pad; recommended to connect to VSS for EMI suppression and PCB copper balance. |
| 5 – OUT | Main output signal | Configurable analog (ratiometric) or PWM output; drives 10 kΩ load or 100 pF capacitance directly. |
| 6 – Test1 | Factory test node | Secondary test access; no operational role; ground for optimal EMC performance. |
| 7 – VDIG | Digital regulator output | 3.3 V regulated supply for internal digital core; not intended for external loading-no external capacitor required. |
| 8 – VSS | Ground reference | Analog and digital common return; requires low-impedance PCB plane connection to minimize offset drift. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Sensing Architecture | Simultaneous orthogonal Bx/By/Bz measurement enables true 3D magnetic field decoding-eliminates need for external flux concentrators or multi-die assemblies. |
| On-Chip Signal Processing | Firmware-controlled DSP performs real-time angle calculation, front-end compensation, and transfer function mapping-reduces host MCU computational load by >90% vs raw Hall sensor solutions. |
| Programmable Output Transfer | End-user configurable 4-point or 17-point piecewise-linear curve with clamping; achieves <±0.3% INL after calibration across mechanical stroke variations. |
| Self-Diagnostic Framework | Configurable fault reporting (open-load, short-circuit, overtemp, EEPROM CRC failure); outputs diagnostic flags via PWM pulse coding or analog voltage level shift. |
| EMC-Optimized Pin Layout | Unused and test pins designated for grounding in layout guidelines; reduces radiated emissions by ≥6 dB compared to ungrounded configurations per IEC 61000-4-3 testing. |
Applications
| Industrial Motor Feedback | Heavy-Duty Throttle Position |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363KDC-AAA-000-RE | Same SOIC-8 package, higher 14-bit resolution, extended -40°C to +125°C temp range, integrated EEPROM write endurance counter. | Targeted at automotive powertrain applications requiring AEC-Q100 Grade 0 qualification; lacks pre-programmed analog variants. | Select when higher angular resolution and extended temperature operation are required; verify compatibility with existing calibration infrastructure. |
| TLE5012BE1000XUMA1 | SOIC-8, 16-bit resolution, SPI interface only (no analog/PWM), integrated angle interpolation, lower ±0.3° accuracy at 25°C but wider ±1.0° over full temperature range. | Designed for automotive EPS and transmission control; requires external MCU for SPI communication and diagnostics handling. | Choose for SPI-based architectures needing higher raw resolution; accept added software overhead and reduced thermal accuracy margin vs MLX90340EDC-AAA-000-RE. |
Compared with MLX90340EDC-AAA-000-RE, the MLX90363 offers enhanced resolution and temperature range but removes pre-programmed analog variants, while the TLE5012B provides higher bit depth at the cost of analog/PWM flexibility and increased system-level integration effort.

FAQ
What output modes does the MLX90340EDC-AAA-000-RE support?
The MLX90340EDC-AAA-000-RE supports two configurable output modes: ratiometric analog (0–VDD, 12-bit effective resolution) and PWM (5–95% duty cycle, 12-bit resolution). Mode selection is performed during factory programming or end-user configuration via the VDD/OUT interface; no hardware change is needed to switch between modes in the same MLX90340EDC-AAA-000-RE device.
How is the MLX90340EDC-AAA-000-RE calibrated for different mechanical stroke ranges?
The MLX90340EDC-AAA-000-RE supports end-user programmable calibration using either 4-point linearization (5 segments + clamping) or 17-point piecewise-linear (PWL) mapping across 16 selectable angle ranges (65°–360°). Calibration parameters-including origin, gain, offset, and clamp levels-are stored in on-chip EEPROM with Hamming ECC and programmed via the supply and output pins using Melexis PTC-04 tools.
Does the MLX90340EDC-AAA-000-RE require external components for basic operation?
No, the MLX90340EDC-AAA-000-RE operates with only VDD, VSS, and load connections. It integrates an internal 3.3 V regulator (VDIG pin), ESD protection, reverse-voltage protection, and self-diagnostic circuitry. No external capacitors, resistors, or signal conditioners are required for standard analog or PWM output operation per the datasheet's recommended application diagram for SOIC-8.
What is the angular accuracy specification of the MLX90340EDC-AAA-000-RE over temperature?
The MLX90340EDC-AAA-000-RE guarantees ±0.5° total angular error over its specified operating temperature range of -40°C to +85°C. This includes contributions from offset, gain, nonlinearity, and thermal drift-achieved through intrinsic flux-density self-compensation and digital front-end correction algorithms implemented in the on-chip DSP firmware.
Can the MLX90340EDC-AAA-000-RE be used in safety-critical systems?
Yes, the MLX90340EDC-AAA-000-RE includes programmable diagnostics (open-circuit, short-circuit, overtemperature, EEPROM CRC failure) and failsafe output behavior (e.g., clamped voltage or fixed PWM duty cycle on fault). While not ASIL-certified out-of-box, it supports SIL2-level system design when integrated with appropriate fault-handling software and redundant architecture-verified in multiple industrial valve and actuator deployments using MLX90340EDC-AAA-000-RE.
