Product details
Overview
MLX90340EDC-AAA-000-SP 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 actuators.
For engineers reviewing the MLX90340EDC-AAA-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package mapping, real-world use cases, and two confirmed alternative parts for position-sensing designs requiring ratiometric analog or PWM output with thermal stability.
Technical Context
The MLX90340EDC-AAA-000-SP integrates three orthogonal Hall plates, a 15-bit ADC, and a 16-bit RISC microcontroller running firmware for CoRDiC-based angle calculation (α = arctan(Bj/Bi)). Its front-end uses chopper-stabilized amplifiers and 2-phase spinning for offset cancellation.
It supports user-programmable 4-point or 17-point piecewise-linear transfer functions, EEPROM-stored calibration with Hamming ECC, and dual-output capability-ratiometric analog (12-bit DAC + buffer) or digital PWM-both configurable via supply/output pins without dedicated programming interfaces.
Key Specifications

| 6 – Test1 | Factory test interface | No functional role in end application; recommended tied to GND for EMC compliance. |
| 7 – VDIG | Internal 3.3 V regulator output | Provides regulated 3.3 V for external logic or diagnostics; supplies up to 5 mA; requires 1 µF decoupling capacitor. |
| 8 – VSS | Ground reference | Analog and digital ground common point; must be low-impedance connection to system GND plane. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous orthogonal Bx/By/Bz measurement enables true absolute angle extraction independent of magnet orientation or axial displacement. |

| Dual Output Mode | Single device delivers either analog (ratiometric, 12-bit) or PWM output-selected via programming-reducing BOM count versus discrete analog+PWM solutions. |
| Self-Diagnostic Capability | On-chip diagnostics detect open-circuit, short-to-rail, and magnetic saturation faults; reports status via output signal modulation or flag pin behavior. |
| Wide Supply Range | 4.5–24 V operation eliminates need for auxiliary regulators in 12/24 V industrial systems, simplifying power architecture and improving reliability. |

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-ABA-000-SP | SOIC-8, same Triaxis® core but with integrated EEPROM lock and enhanced EMC filtering; 12-bit analog/PWM output; -40°C to +125°C rating. | Targeted at automotive-grade applications requiring AEC-Q100 qualification and higher junction temperature margin. | Select when operating ambient exceeds +85°C or when production-line programming lock is required for IP protection. |
| AS5055A-DSOT | TSSOP-16, 14-bit resolution, SPI interface only (no analog/PWM), ±0.3° accuracy, 3.3 V supply only. | Requires external MCU for digital communication and signal processing; lacks on-chip transfer function programming. | Select when digital bus integration (SPI) is preferred and system-level calibration can be handled in host firmware. |
Compared with MLX90340EDC-AAA-000-SP, MLX90363KDC-ABA-000-SP offers extended temperature range and hardware programming lock for secure calibration, while AS5055A-DSOT trades analog/PWM flexibility for higher resolution and digital interface-but demands host-side computation and external regulation.

FAQ
What output modes does the MLX90340EDC-AAA-000-SP support?
The MLX90340EDC-AAA-000-SP supports two user-selectable output modes: ratiometric analog voltage (0–VDD, 12-bit effective resolution) and digital PWM (12-bit duty-cycle resolution). Both modes are programmed via the supply and output pins using Melexis' PTC-04 programmer and DB90316 software tools-no dedicated interface pins are required. The MLX90340EDC-AAA-000-SP retains its configuration in EEPROM after power cycling.
Does the MLX90340EDC-AAA-000-SP require external magnets, and what type is recommended?
Yes, the MLX90340EDC-AAA-000-SP requires an external diametrically or radially magnetized permanent magnet positioned above the IC's sensitive spot. Melexis recommends NdFeB or SmCo magnets with surface field strength between 100–300 mT; optimal placement aligns the magnet's rotational axis with the IC's X-Y plane. The MLX90340EDC-AAA-000-SP's Triaxis® architecture tolerates ±1 mm air gap variation and ±5° tilt without accuracy loss.
How is the MLX90340EDC-AAA-000-SP calibrated for custom transfer functions?
The MLX90340EDC-AAA-000-SP supports two calibration methods: 4-point linear interpolation (5-segment curve + clamping) or 17-point piecewise-linear (PWL) mapping across 65–360° ranges. Calibration parameters-including offset, gain, clamp limits, and discontinuity points-are programmed into on-chip EEPROM using the Melexis PTC-04 tool and stored with Hamming ECC for error correction. The MLX90340EDC-AAA-000-SP applies these settings autonomously during operation.
What is the thermal accuracy specification of the MLX90340EDC-AAA-000-SP?
The MLX90340EDC-AAA-000-SP achieves 10-bit thermal accuracy (±0.1% of full scale per °C), meaning its output deviation due to temperature drift remains bounded within 0.1% FS/°C across -40°C to +85°C. This is enabled by on-chip front-end compensation and DSP-based thermal modeling-not external components-so the MLX90340EDC-AAA-000-SP delivers stable position data without recalibration in varying ambient conditions.
Can the MLX90340EDC-AAA-000-SP be used in safety-critical systems?
The MLX90340EDC-AAA-000-SP includes built-in self-diagnostics for open-circuit, short-to-rail, and magnetic saturation faults, reporting via output signal modulation or flag behavior. While it is not ASIL-certified, its dual-die TSSOP-16 variant (MLX90340EGO-AAA-000-SP) supports full redundancy. For single-die use like the MLX90340EDC-AAA-000-SP, system-level fault handling must be implemented externally-e.g., watchdog timers or cross-checking with secondary sensors-to meet SIL2 or ASIL-B requirements.
