Product details
Overview
MLX90340SDC-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 integrated signal processing in SOIC-8 package. It replaces contact potentiometers in industrial valve actuation, steering angle feedback, and throttle position systems.
For engineers reviewing the MLX90340SDC-AAA-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, real-world use cases, and validated alternative options for non-contacting position sensing designs requiring thermal stability and field-programmability.
Technical Context
The MLX90340SDC-AAA-000-RE integrates three orthogonal Hall plates (Bx, By, Bz) with a 15-bit ADC and 16-bit RISC microcontroller running firmware for CoRDiC-based angular calculation. Its DSP performs front-end compensation, multi-point linearization (4-pt LNR or 17-pt PWL), and real-time clamping/offset/gain adjustment.
It supports ratiometric analog output (0–VDD, 12-bit DAC) or digital PWM (12-bit resolution, 500 Hz–2 kHz configurable frequency), both programmable via supply/output pins without dedicated programming interfaces. The device features EEPROM with Hamming ECC for calibration storage and built-in self-diagnostics including open-circuit, short-circuit, and magnetic saturation detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Selectable ratiometric analog (0–VDD) or PWM (500 Hz–2 kHz); enables direct MCU ADC interface or robust noise-immune digital transmission. |
| Resolution | 12-bit output resolution with 10-bit thermal accuracy; ensures stable position reporting across temperature without external compensation. |
| Angular Accuracy | ±0.5° typical over full scale; achieved via Triaxis® vector computation and factory-calibrated front-end compensation. |
| Operating Temp | -40°C to +85°C (Industrial grade); validated for under-hood and factory automation environments with no derating. |
| Supply Voltage | 4.5 V to 5.5 V; compatible with standard 5 V logic rails and automotive subsystems with regulated supplies. |
| Magnetic Range | ±1 T (±10 kG); supports high-field magnets in compact mechanical layouts without signal saturation. |
| Package | SOIC-8; surface-mount footprint with 1.27 mm pitch, RoHS-compliant, qualified for reflow soldering per JEDEC J-STD-020. |
Pinout & Package
MLX90340SDC-AAA-000-RE uses the SOIC-8 package (JEDEC MS-012AC), with 1.27 mm lead pitch, 5.0 mm × 4.0 mm body, and exposed die pad not electrically connected. Unused test pins must be grounded for EMC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – VDD | Power supply input | 4.5–5.5 V nominal supply; internal reverse-voltage protection to -12 V prevents damage during polarity reversal. |
| 2 – Test Input | Factory test node | No user function; must be connected to GND per datasheet for optimal EMC performance. |
| 3 – Test | Factory test node | No user function; tie to GND to minimize noise coupling into analog signal chain. |
| 4 – Not Used | Unbonded pad | Internally unconnected; connect to GND to reduce parasitic capacitance and improve ESD immunity. |
| 5 – OUT | Main output terminal | Drives ratiometric analog voltage (0–VDD) or PWM signal; buffered output capable of 5 mA sink/source. |
| 6 – Test1 | Factory test node | No operational role; grounding required to suppress high-frequency emissions. |
| 7 – VDIG | Digital regulator output | Internal 3.3 V regulator output; powers digital core and EEPROM; decoupling capacitor required at pin. |
| 8 – VSS | Ground reference | Analog/digital common ground; low-impedance return path essential for 12-bit linearity and thermal accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx, By, Bz measurement enables true absolute angle decoding without external magnets or complex assemblies. |
| Programmable Transfer Curve | 4-point or 17-point piecewise-linear calibration allows precise matching to mechanical stroke profiles (e.g., 0–90°, 0–360°). |
| On-Chip Signal Processing | Firmware-controlled DSP eliminates need for external microcontroller in basic position-sensing applications. |
| EEPROM with ECC | 48-bit ID + calibration data stored in NVRAM with Hamming error correction ensures field reliability over 100k write cycles. |
| Self-Diagnostic Capability | Detects open-circuit, short-to-rail, magnetic saturation, and internal fault conditions-critical for ASIL-B–compatible systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365EDC-ABB-000-RE | Higher angular accuracy (±0.3°), extended magnetic range (±1.5 T), but fixed 360° pre-programmed analog output only. | Limited to fixed-range applications; lacks user-programmable transfer curve and PWM option. | Choose when highest precision is required and mechanical range is strictly 0–360° with no field recalibration needs. |
| TLE5012BEEAUMA1 | Infineon's 3D Hall sensor with 16-bit SPI output, integrated SENT interface, and higher ESD rating (8 kV HBM), but requires external MCU for processing. | Requires host processor for angle computation and calibration; no on-chip DSP or EEPROM storage. | Choose when system already includes a capable MCU and SENT protocol integration is preferred over analog/PWM simplicity. |
Compared with MLX90340SDC-AAA-000-RE, MLX90365EDC-ABB-000-RE trades programmability for tighter accuracy, while TLE5012BEEAUMA1 shifts signal processing burden to the host-making MLX90340SDC-AAA-000-RE optimal for cost-sensitive, self-contained position sensing with field adaptability.

FAQ
What is the operating temperature range for the MLX90340SDC-AAA-000-RE?
The MLX90340SDC-AAA-000-RE is rated for industrial operation from -40°C to +85°C. This range is confirmed in the official Melexis datasheet Revision 2-31AUG2020, Section 4 (Ordering Information), where "E" temperature code explicitly defines this specification. It does not support extended automotive (-40°C to +150°C) or consumer-grade ranges.
Does the MLX90340SDC-AAA-000-RE support both analog and PWM outputs simultaneously?
No, the MLX90340SDC-AAA-000-RE supports only one output mode at a time-either ratiometric analog (0–VDD) or PWM-selected during programming. The datasheet Section 17.1 confirms that output mode is a mutually exclusive configuration stored in EEPROM; dual-output operation is not implemented in hardware or firmware for this variant.
Can the MLX90340SDC-AAA-000-RE be programmed in-system after soldering?
Yes, the MLX90340SDC-AAA-000-RE supports in-system programming via its VDD and OUT pins using the Melexis PTC-04 programmer and DB90316 software tools. No dedicated programming pins are required, and the process works on assembled PCBs, enabling field calibration and transfer curve updates without device removal.
What is the meaning of "AAA-000" in MLX90340SDC-AAA-000-RE?
In MLX90340SDC-AAA-000-RE, "AAA-000" denotes the standard version with no pre-programmed transfer function. As defined in Table 1 of the datasheet, "000" indicates a blank calibration state-users must program offset, gain, clamping, and linearity points post-manufacture to match their specific mechanical layout and magnetic circuit.
Is the SOIC-8 package of MLX90340SDC-AAA-000-RE RoHS compliant and lead-free?
Yes, the MLX90340SDC-AAA-000-RE SOIC-8 package is RoHS compliant and lead-free, as stated in Section 1 (Features and Benefits) of the datasheet: "Single Die – SOIC-8 Package RoHS Compliant." It meets EU Directive 2011/65/EU and is qualified for Pb-free reflow soldering per JEDEC J-STD-020.
