Product details
Overview
MLX90340EDC-AAA-100-SP from Melexis is a monolithic Triaxis® Hall-effect IC for absolute rotary position sensing with 12-bit analog output, ratiometric transfer function pre-programmed for 90° range (80%VDD/90°), and SOIC-8 package. It decodes Bx, By, Bz flux components to deliver robust non-contact angular measurement in harsh industrial environments.
For engineers reviewing the MLX90340EDC-AAA-100-SP datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, SOIC-8 terminal mapping, real-world use cases in heavy-duty rotary feedback, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MLX90340EDC-AAA-100-SP implements a fully differential analog front-end with chopper-stabilized amplification and 15-bit ADC digitization, followed by a 16-bit RISC microcontroller executing firmware-based CoRDiC angular computation. Its DSP engine processes raw Hall signals to extract magnetic angle α = arctan(Bj/Bi) with intrinsic thermal compensation.
It supports user-programmable output transfer characteristics via EEPROM-stored 4-point linear or 17-point piecewise-linear calibration, with Hamming ECC protection. The device outputs a ratiometric analog signal (12-bit DAC + buffer) pre-configured for 90° mechanical rotation, delivering 0.8×VDD full-scale swing over that range.

| 1 - VDD | Power supply input | Accepts 4.5–24 V DC; internal reverse-voltage protection up to -12 V prevents damage during polarity reversal |
| 2 - Test Input | Factory test interface | No user function; recommended to connect to GND for EMC stability |
| 3 - Test | Factory test interface | No user function; recommended to connect to GND for EMC stability |
| 4 - Not Used | Unbonded pad | Must be connected to VSS to minimize parasitic coupling and improve ESD robustness |
| 5 - OUT | Analog output | Ratiometric voltage output (0–0.8×VDD) scaled to 0–90° mechanical rotation; drives 1 kΩ load minimum |
| 6 - Test1 | Factory test interface | No user function; recommended to connect to GND for EMC stability |
| 7 - VDIG | Internal 3.3 V regulator output | Provides regulated 3.3 V for internal digital core; not intended for external loading |
| 8 - VSS | Ground reference | Primary return path for analog and digital sections; requires low-impedance PCB connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-axis Hall sensing | Enables absolute position decoding from a single moving magnet without requiring orthogonal magnet placement or multi-sensor arrays |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363EDC-AAA-100-SP | Same SOIC-8 package and 90° pre-programmed analog output, but adds integrated diagnostics (open/short wire, overtemp) and enhanced EMC filtering | Required where ISO 26262 ASIL-B compliance or diagnostic coverage reporting is mandated | Select MLX90363EDC-AAA-100-SP when functional safety evidence (FMEDA, diagnostic coverage) is needed beyond basic position accuracy |
| AS5055A-DSOM | 12-bit SPI-output magnetic encoder in 16-pin TSSOP; no analog/PWM output; requires external MCU for processing | Suitable only in designs with available SPI interface and host processor resources for angle computation | Choose AS5055A-DSOM if system already uses SPI peripherals and requires higher resolution (14-bit) with programmable zero point, but accept added software overhead |
Compared with MLX90340EDC-AAA-100-SP, MLX90363EDC-AAA-100-SP adds safety-critical diagnostics without changing pinout or analog behavior, while AS5055A-DSOM shifts responsibility for transfer function execution to the host MCU - making MLX90340EDC-AAA-100-SP optimal for cost-sensitive, self-contained analog feedback loops.

FAQ
What is the output voltage range of the MLX90340EDC-AAA-100-SP?
The MLX90340EDC-AAA-100-SP provides a ratiometric analog output ranging from 0 V to 0.8×VDD, calibrated for 0–90° mechanical rotation. At VDD = 12 V, this yields 0–9.6 V output; at VDD = 5 V, it delivers 0–4.0 V. The output is buffered and specified to drive ≥1 kΩ loads without gain error.
Does the MLX90340EDC-AAA-100-SP require external programming for its 90° transfer function?
No - the MLX90340EDC-AAA-100-SP ships with factory-programmed 90° analog transfer characteristics stored in EEPROM. No external programming unit (e.g., PTC-04) or calibration steps are needed for basic operation. The device powers up ready to deliver accurate position data immediately upon supply application.
Can the MLX90340EDC-AAA-100-SP operate from a 24 V supply rail?
Yes - the MLX90340EDC-AAA-100-SP supports supply voltages from 4.5 V to 24 V DC. Its internal regulator and protection circuitry enable direct connection to 24 V industrial buses. At 24 V, the analog output scales to 0–19.2 V, maintaining full 12-bit resolution and ratiometric accuracy.
What is the role of the VDIG pin on the MLX90340EDC-AAA-100-SP?
The VDIG pin on the MLX90340EDC-AAA-100-SP supplies 3.3 V to the internal digital core (DSP, EEPROM, logic). It is an output pin - not an input - and must not be loaded externally. Connecting any external circuitry to VDIG may disrupt internal voltage regulation and cause functional failure of the MLX90340EDC-AAA-100-SP.
How does the MLX90340EDC-AAA-100-SP achieve thermal accuracy better than conventional Hall sensors?
The MLX90340EDC-AAA-100-SP achieves ±10-bit thermal accuracy through on-chip DSP-based compensation of Hall plate offset and sensitivity drift. Its Triaxis® architecture measures all three magnetic vector components, enabling algorithmic rejection of temperature-induced gain/offset errors - unlike single-axis Hall sensors that require external thermistors or complex calibration tables.
