Product details
Overview
MLX90340SDC-AAA-100-RE from Melexis is a monolithic Triaxis® Hall-effect IC for absolute rotary position sensing with 90° 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 industrial motor control and heavy-duty actuation systems.
For engineers reviewing the MLX90340SDC-AAA-100-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SOIC-8 pin mapping, programmable transfer function details, thermal accuracy validation, and direct alternatives for analog-output position sensing designs requiring 90° range and industrial temperature grade.
Technical Context
The MLX90340SDC-AAA-100-RE implements a fully differential analog front-end with chopper-stabilized amplification and 15-bit ADC digitization of three orthogonal Hall voltages (VX, VY, VZ), followed by DSP-based CoRDiC angular computation. Its firmware executes real-time front-end compensation and angle extraction using two raw signals per calculation cycle.
It supports only pre-programmed analog output mode with fixed 90° measurement range and 80%VDD transfer slope, as defined by AAA-100 option code. No PWM or user reprogramming is enabled - output is ratiometric, buffered, and clamped per factory calibration stored in ECC-protected NVRAM.

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-AAA-000-RE | SOIC-8, 360° programmable analog/PWM output, user-configurable via PTC-04; same Triaxis® core and accuracy | Requires post-manufacture programming; supports wider angular ranges and dual-output flexibility | Select when design needs field-adjustable range or future-proofing for multi-angle variants |
| AS5055A-DSOM | 12-bit SPI output only; no analog/PWM; 360° range; QFN-16 package; lower temp grade (-40°C to +85°C) | Requires external ADC or microcontroller interface; lacks ratiometric analog simplicity and integrated diagnostics | Select when digital interface preferred and board space allows QFN-16; verify diagnostic coverage against system ASIL requirements |
Compared with MLX90340SDC-AAA-100-RE, MLX90363KDC-AAA-000-RE offers programmability at the cost of added production steps, while AS5055A-DSOM trades analog simplicity for digital flexibility and reduced on-chip intelligence - making MLX90340SDC-AAA-100-RE optimal for drop-in analog replacement of legacy potentiometers in industrial settings.

FAQ
What is the angular measurement range of the MLX90340SDC-AAA-100-RE?
The MLX90340SDC-AAA-100-RE is factory pre-programmed for a fixed 90° absolute angular measurement range, corresponding to its AAA-100 option code. This range is hard-coded in firmware and cannot be modified in the field. The output voltage scales linearly from 0.1×VDD at 0° to 0.9×VDD at 90°, enabling direct interface with standard 10-bit or higher ADCs without signal conditioning.
Does the MLX90340SDC-AAA-100-RE support PWM output?
No, the MLX90340SDC-AAA-100-RE does not support PWM output. Its AAA-100 configuration locks the device exclusively to ratiometric analog output mode. Unlike other MLX90340 variants (e.g., AAA-000), this version omits PWM functionality and all user programming interfaces - it is delivered fully calibrated and ready for immediate use in analog-feedback systems.
What is the operating temperature range for MLX90340SDC-AAA-100-RE?
The MLX90340SDC-AAA-100-RE operates over -40°C to +85°C, as indicated by its 'E' temperature code in the ordering nomenclature. This industrial-grade rating is validated per Melexis datasheet Section 8 (Absolute Maximum Ratings) and Section 13 (Accuracy), with ±1.0° maximum angular error across the full range - making it suitable for factory automation, HVAC actuators, and non-under-hood automotive subsystems.
Can MLX90340SDC-AAA-100-RE be used in safety-critical applications?
The MLX90340SDC-AAA-100-RE includes on-chip self-diagnostics (supply monitoring, EEPROM integrity, signal path validation) and meets ASIL-B capability per ISO 26262 when integrated into a properly architected system. However, it is not ASIL-certified out-of-the-box. System-level validation is required. For ASIL-B–compliant designs, pairing MLX90340SDC-AAA-100-RE with redundant sensing or cross-checking logic is recommended.
Is the SOIC-8 package of MLX90340SDC-AAA-100-RE RoHS-compliant and lead-free?
Yes, the MLX90340SDC-AAA-100-RE uses a RoHS-compliant, lead-free SOIC-8 package per Melexis documentation (Section 1, Features and Benefits). It conforms to JEDEC MS-012AC standards and supports standard SnAgCu reflow profiles. The package contains no exempted leaded solder balls or internal lead frames - full compliance is confirmed in Melexis's Declaration of Conformity and material content reports.
