Product details
Overview
MLX90340SDC-AAA-200-SP from Melexis is a monolithic Triaxis® Hall-effect IC for absolute rotary position sensing up to 360°, featuring 12-bit analog ratiometric output, programmable linear transfer characteristic (17-point piecewise-linear), and SOIC-8 packaging. It operates from -40°C to +85°C with ±1% full-scale accuracy and supports non-contacting potentiometer replacement in industrial motor feedback systems.
For engineers reviewing the MLX90340SDC-AAA-200-SP datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, SOIC-8 terminal mapping, real-world use cases in heavy-duty rotary sensing, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The MLX90340SDC-AAA-200-SP integrates three orthogonal Hall plates (Bx, By, Bz) and a 16-bit RISC microcontroller running firmware-based CoRDiC angular computation. Its analog front-end uses chopper-stabilized amplifiers and 2-phase spinning for offset cancellation, enabling intrinsic thermal drift compensation.
It implements a fully programmable 12-bit DAC-based analog output stage pre-configured for 360° range (80% VDD per full rotation), with EEPROM-stored calibration data protected by Hamming ECC. The device requires no external programming pins-configuration occurs via VDD/OUT signaling using the PTC-04 programmer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365KGO-ABA-000-SP | Dual-die TSSOP-16 package with full hardware redundancy; 16-bit resolution; supports both analog and PWM outputs simultaneously | Required for ASIL-D automotive safety systems; higher cost and PCB area vs. MLX90340SDC-AAA-200-SP | Select when functional safety certification (ISO 26262) and dual-channel fault detection are mandatory |
| AS5055A-DSOT | 14-bit SPI-output magnetic encoder; no integrated analog/PWM driver; requires external ADC or MCU processing | Suitable for space-constrained designs where digital interface and lower power (3.3 V only) are prioritized over analog simplicity | Select when system already includes high-speed SPI infrastructure and firmware can handle angle computation and scaling |
Compared with MLX90340SDC-AAA-200-SP, the MLX90365 offers certified redundancy but increases BOM cost and layout complexity, while the AS5055A shifts signal conditioning burden to the host MCU - making MLX90340SDC-AAA-200-SP optimal for cost-sensitive industrial analog interfaces requiring drop-in replacement of potentiometers.

FAQ
What is the default output transfer function of the MLX90340SDC-AAA-200-SP?
The MLX90340SDC-AAA-200-SP is factory pre-programmed with a 360° linear analog transfer function: output voltage scales ratiometrically from 0% to 80% of VDD across 0° to 360° of mechanical rotation. This configuration eliminates the need for field calibration in standard rotary applications and ensures immediate usability upon power-up.
Does the MLX90340SDC-AAA-200-SP require external programming to operate?
No, the MLX90340SDC-AAA-200-SP is fully functional out-of-the-box. Its 360° analog transfer characteristic is permanently stored in EEPROM during manufacturing. No external programmer, host MCU, or configuration sequence is needed - simply apply VDD and read the analog output on pin 5 (OUT).
Can the MLX90340SDC-AAA-200-SP be used in automotive applications?
The MLX90340SDC-AAA-200-SP is rated for -40°C to +85°C ambient operation and meets industrial EMC standards, but it is not AEC-Q100 qualified. For automotive applications requiring ASIL compliance or extended temperature range (-40°C to +125°C or +150°C), Melexis recommends the MLX90365 or MLX90393 series instead of the MLX90340SDC-AAA-200-SP.
What is the purpose of the VDIG pin on the MLX90340SDC-AAA-200-SP?
The VDIG pin (pin 7) provides a regulated 3.3 V output from the MLX90340SDC-AAA-200-SP's internal LDO, powering its digital core including the microcontroller, EEPROM, and DSP. A 100 nF ceramic capacitor must be placed between VDIG and VSS to ensure stable operation and low-noise digital supply.
How does the MLX90340SDC-AAA-200-SP achieve thermal accuracy better than conventional Hall sensors?
The MLX90340SDC-AAA-200-SP achieves ±1% full-scale thermal accuracy by combining Triaxis® 3D magnetic sensing with on-chip DSP-based angular computation that intrinsically compensates for flux density variations across temperature. Unlike single-axis Hall sensors, its CoRDiC algorithm derives angle from vector ratios (e.g., arctan(Bx/By)), making output independent of absolute field strength drift.
