Product details
Overview
MLX90340EDC-AAA-300-SP from Melexis is a monolithic Triaxis® Hall-effect IC for absolute rotary position sensing with 180° pre-programmed ratiometric analog output, 12-bit resolution, ±0.5° angular accuracy over -40°C to +85°C, and SOIC-8 package. It decodes Bx/By/Bz magnetic vector components to deliver robust non-contact position feedback in industrial motor control and valve actuation systems.
For engineers reviewing the MLX90340EDC-AAA-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, programmable transfer characteristics, thermal accuracy data, and validated alternative options for absolute position sensing designs requiring 180° analog output range and industrial temperature operation.
Technical Context
The MLX90340EDC-AAA-300-SP implements Triaxis® technology to measure orthogonal (Bz) and in-plane (Bx, By) magnetic flux components simultaneously using integrated Hall plates. Its on-chip DSP computes angular position via CoRDiC-based arctangent calculation from two raw Hall signals, enabling intrinsic compensation for flux density variations.
Signal processing includes 15-bit ADC conversion, firmware-controlled front-end compensation, and programmable 4-point or 17-point piecewise-linear (PWL) transfer function mapping. Output is delivered as a ratiometric analog voltage (0–80% VDD over 180°) with 12-bit DAC buffering, pre-configured per AAA-300 option.

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-300-SP | Same SOIC-8 package and 180° analog output, but adds integrated EEPROM for user-programmable diagnostics and clamping | Supports field recalibration and fault logging; requires PTC-04 programmer for configuration | Select when diagnostic traceability or post-deployment parameter tuning is required |
| AMS AS5055A-DSO | 12-bit SPI-output magnetic encoder in SOIC-8; no pre-programmed analog output - requires external DAC or MCU processing | Delivers raw angle data only; lacks built-in ratiometric analog driver and 180° transfer function | Select when digital interface and flexible firmware-defined output scaling are preferred over plug-and-play analog |
Compared with MLX90340EDC-AAA-300-SP, MLX90363EDC-AAA-300-SP adds field-programmable diagnostics but shares identical analog output behavior, while AMS AS5055A-DSO shifts design responsibility to the host MCU for signal conditioning and transfer function implementation.

FAQ
What is the output voltage range of the MLX90340EDC-AAA-300-SP?
The MLX90340EDC-AAA-300-SP provides a ratiometric analog output ranging from 0 V to 80% of VDD across its pre-programmed 180° mechanical rotation range. For example, with VDD = 5 V, output spans 0–4.0 V linearly; with VDD = 12 V, it spans 0–9.6 V. This scaling maintains proportionality to supply voltage, eliminating need for external voltage references.
Does the MLX90340EDC-AAA-300-SP require external programming for its 180° analog output?
No, the MLX90340EDC-AAA-300-SP is factory-programmed with the AAA-300 option, configuring it for 180° mechanical range and 0–80% VDD analog transfer characteristic. No external tools, PTC-04 programmer, or firmware upload are needed - it operates immediately upon power-up with defined output behavior.
Can the MLX90340EDC-AAA-300-SP be used in safety-critical automotive steering angle sensing?
The MLX90340EDC-AAA-300-SP meets key functional requirements for steering angle sensing - including ±0.5° accuracy, 12-bit resolution, and 2.5 ms latency - and is used in ASIL-B compliant systems. However, full ASIL-B certification requires system-level validation; Melexis provides FIT rate data and diagnostic coverage reports to support ISO 26262 integration of MLX90340EDC-AAA-300-SP.
What is the recommended grounding practice for unused pins on the MLX90340EDC-AAA-300-SP?
Per Melexis datasheet Section 7.1, pins 2 (Test Input), 3 (Test), 4 (Not Used), and 6 (Test1) must be connected to VSS (pin 8) to ensure optimal EMC performance. This grounding reduces radiated emissions and improves noise immunity in electrically noisy industrial environments where MLX90340EDC-AAA-300-SP is commonly deployed.
How does the Triaxis® technology in the MLX90340EDC-AAA-300-SP improve thermal accuracy compared to conventional Hall sensors?
The MLX90340EDC-AAA-300-SP uses Triaxis® technology to measure all three magnetic vector components (Bx, By, Bz) and compute angle via CoRDiC arctangent, enabling intrinsic compensation for flux density variations with temperature. This architecture achieves ±0.5° thermal accuracy over -40°C to +85°C - significantly better than single-axis Hall sensors whose offset and sensitivity drift directly with temperature.
