Product details
Overview
MLX90340SDC-AAA-200-RE from Melexis is a Triaxis® Hall-effect absolute rotary position sensor IC in SOIC-8 package, delivering 360° pre-programmed ratiometric analog output with 12-bit resolution, ±0.5° typical angular accuracy over -40°C to +85°C, and integrated signal processing for non-contacting industrial position sensing.
For engineers reviewing the MLX90340SDC-AAA-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, SOIC-8 terminal mapping, real-world use cases in heavy-duty rotary feedback, and validated alternative options for analog-output magnetic position sensing.
Technical Context
The MLX90340SDC-AAA-200-RE integrates three orthogonal Hall plates (Bx, By, Bz) with a 15-bit ADC and 16-bit RISC DSP to compute magnetic angle via CoRDiC-based coordinate rotation, enabling intrinsic thermal compensation and high linearity without external calibration hardware.
It implements a fixed 360° linear transfer function (80% VDD full-scale) stored in EEPROM, supports ratiometric analog output only (no PWM), and uses on-chip ROM firmware to manage front-end compensation, clamping, and self-diagnostics - all configured via supply/output pins without dedicated programming interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute analog-output magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363KDC-AAA-000-RE | Same SOIC-8 package; offers programmable 0–360° analog/PWM dual output; requires end-user programming | Used where flexible transfer curve tuning or diagnostic reporting is needed post-deployment | Select when design requires field-adjustable output scaling or PWM fallback capability |
| TLE5012BE1500XUMA1 | SOIC-8; 14-bit resolution; SPI digital output only; no analog voltage output | Requires external ADC or MCU with SPI interface; not drop-in compatible for analog-input systems | Select when digital communication, higher resolution, or AEC-Q100 Grade-1 qualification is mandatory |
Compared with MLX90340SDC-AAA-200-RE, the MLX90363 offers greater flexibility but adds programming complexity, while the TLE5012B delivers higher precision and automotive qualification at the cost of analog interface compatibility - making MLX90340SDC-AAA-200-RE optimal for plug-and-play industrial analog feedback.

FAQ
What is the output voltage range of the MLX90340SDC-AAA-200-RE?
The MLX90340SDC-AAA-200-RE delivers a ratiometric analog output ranging from 0.1 × VDD to 0.9 × VDD, corresponding linearly to 0°–360° position. At VDD = 5 V, this yields 0.5–4.5 V; at VDD = 12 V, it yields 1.2–10.8 V. This scaling ensures consistent performance across varying supply voltages in industrial power rails.
Does the MLX90340SDC-AAA-200-RE require external programming for 360° operation?
No - the MLX90340SDC-AAA-200-RE is factory pre-programmed for 360° linear analog output (80% VDD full-scale). No external tools, PTC-04 programmer, or firmware upload is needed. It operates immediately upon power-up with fixed transfer characteristics defined in ordering code "AAA-200".
Can the MLX90340SDC-AAA-200-RE be used in automotive applications?
The MLX90340SDC-AAA-200-RE is rated for -40°C to +85°C and meets industrial EMC requirements, but it is not AEC-Q200 qualified. For automotive under-hood use, Melexis recommends the MLX90340LGO-AAA-xxx-RE (TSSOP-16 dual-die, -40°C to +150°C) or MLX90363 variants with full automotive qualification.
What is the purpose of the VDIG pin on the MLX90340SDC-AAA-200-RE?
The VDIG pin on the MLX90340SDC-AAA-200-RE outputs a regulated 3.3 V supply generated internally to power the DSP, EEPROM, and digital logic blocks. A 100 nF ceramic capacitor must be placed between VDIG and VSS to ensure stable operation and low-noise digital performance.
How does the MLX90340SDC-AAA-200-RE achieve thermal accuracy better than conventional Hall sensors?
The MLX90340SDC-AAA-200-RE achieves ±0.5° thermal accuracy by using Triaxis® 3D Hall sensing combined with on-chip DSP-based front-end compensation and CoRDiC angle computation - which intrinsically cancels flux density variations and temperature-induced gain/offset drift, unlike single-axis Hall sensors requiring external compensation.
