Product details
Overview
MLX90340EDC-AAA-300-RE 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 vector components to deliver robust non-contact position feedback in automotive throttle valves and industrial rotary actuators.
For engineers reviewing the MLX90340EDC-AAA-300-RE datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, SOIC-8 terminal mapping, pre-configured 180° analog transfer function details, thermal accuracy validation, and direct alternatives for heavy-duty position sensing designs.
Technical Context
The MLX90340EDC-AAA-300-RE integrates a tri-axis Hall front-end, 15-bit ADC, 16-bit RISC microcontroller, and on-chip DSP firmware to compute magnetic angle via CoRDiC-based arctan(Bj/Bi) calculation. Its analog signal chain uses chopper-stabilized amplifiers and 2-phase spinning for offset cancellation.
This variant is factory-programmed for 180° angular range with 80% VDD output span (0.8 × VDD over 0–180°), ratiometric analog output, and clamped linear transfer characteristic. It operates from 4.5 V to 24 V supply and supports self-diagnostic reporting without external pins.

FAQ
What is the factory-programmed angular range of the MLX90340EDC-AAA-300-RE?
The MLX90340EDC-AAA-300-RE is factory-programmed for a 180° absolute angular range, delivering a ratiometric analog output spanning 0 V to 0.8 × VDD across 0–180°. This fixed transfer function eliminates field programming and ensures immediate plug-and-play integration in rotary applications such as throttle valves and damper actuators. The MLX90340EDC-AAA-300-RE does not require external calibration to achieve its specified ±0.5° thermal accuracy.
Does the MLX90340EDC-AAA-300-RE support PWM output mode?
No, the MLX90340EDC-AAA-300-RE is configured exclusively for ratiometric analog output. While the base MLX90340 architecture supports selectable analog or PWM output, the AAA-300 option code specifically locks the device to analog mode with 180° pre-programming. To obtain PWM functionality, a different option code (e.g., AAA-000) or custom programming via PTC-04 is required - the MLX90340EDC-AAA-300-RE itself cannot be reconfigured in-system.
What is the role of the VDIG pin on the MLX90340EDC-AAA-300-RE?
The VDIG pin on the MLX90340EDC-AAA-300-RE provides the regulated 3.3 V supply for the internal digital core, including the 16-bit RISC microcontroller and EEPROM. It must be decoupled with a 100 nF capacitor to ground. Unlike VDD, VDIG is an output - not an input - and cannot be used to power external circuitry. This dedicated rail isolates noise-sensitive digital logic from the main analog supply, contributing to the MLX90340EDC-AAA-300-RE's robust EMC performance.
Can unused pins on the MLX90340EDC-AAA-300-RE be left floating?
No, unused pins (Pin 4 "Not Used", Pins 2/3/6 "Test") on the MLX90340EDC-AAA-300-RE must be connected to VSS (ground) to ensure optimal electromagnetic compatibility. Melexis explicitly recommends this in the datasheet to suppress parasitic coupling and reduce radiated emissions. Leaving these pins floating may degrade noise immunity and cause erratic output behavior, especially in high-EMI environments like automotive engine bays or industrial motor drives.
How does the MLX90340EDC-AAA-300-RE achieve ±0.5° thermal accuracy?
The MLX90340EDC-AAA-300-RE achieves ±0.5° thermal accuracy through on-chip DSP compensation of temperature-dependent gain and offset errors in the Triaxis® front-end, combined with chopper-stabilized amplifiers and 2-phase Hall plate spinning. Its firmware performs real-time correction using stored calibration coefficients, resulting in 10-bit effective thermal stability over -40°C to +85°C - a key advantage over linear Hall sensors that lack vector-based self-compensation. This accuracy is guaranteed for the MLX90340EDC-AAA-300-RE's pre-programmed 180° range.
