Product details
Overview
MLX90366LVS-ADS-250-RE from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect 3D magnetic field sensing (Bx, By, Bz) to deliver 12-bit angular/linear position output via SENT protocol (SAE J2716-2010), with 17-point programmable transfer characteristic, on-board diagnostics, and automotive-grade thermal stability (−40°C to +150°C). It enables non-contacting rotary or linear position sensing in throttle, pedal, and steering systems.
For engineers reviewing the MLX90366LVS-ADS-250-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, thermal offset correction capability (excluded in ADS variant), DMP-4 package mapping, and real-world diagnostic behavior for automotive sensor integration.
Technical Context
The MLX90366LVS-ADS-250-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time coordinate rotation (CoRDiC) to compute absolute angle from orthogonal magnetic field components. Its SENT output conforms to Throttle Sensor format with fast-channel diagnostics and slow-channel enhanced serial messages.
It features factory-trimmed intrinsic linearity error of ±1° (XY axis), 17-point piecewise-linear (LNR) transfer function programmability, and configurable FIR filtering (FILTER=0/1/2) with typical latency of 1745 μs (FILTER=1). Magnetic sensitivity is calibrated via SMISM and k parameters, supporting IMC-based flux concentration up to 126 mT (Bz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90366LVS-AEV-250-RE | Same DMP-4 package and SENT interface; supports 17-point LNR plus thermal output offset correction (not available in ADS-xxx) | Required where thermal drift compensation is critical (e.g., under-hood engine bay mounting with >100°C ambient swings) | Select AEV-xxx when thermal offset correction is needed; ADS-xxx lacks this feature per datasheet Section 14.1.6 |
| MLX90366LVS-AEX-250-RE | Includes thermal output offset correction and enhanced EEPROM endurance; same 17-point LNR capability as ADS-xxx | Suitable for long-life modules requiring >100k write cycles to EEPROM (e.g., industrial actuators with frequent recalibration) | Choose AEX-xxx for extended EEPROM endurance and thermal correction; ADS-xxx has standard EEPROM spec per Section 14.7 |
Compared with MLX90366LVS-ADS-250-RE, the AEV-xxx variant adds thermal offset correction for improved high-temperature accuracy, while AEX-xxx further extends EEPROM endurance-both retain identical SENT timing, pinout, and 17-point programmability, making them drop-in replacements only when those specific features are required.

FAQ
What is the SENT frame structure used by MLX90366LVS-ADS-250-RE?
The MLX90366LVS-ADS-250-RE implements the SAE J2716-2010 Throttle Sensor format: each SENT frame contains 12 nibbles (48 bits), including 16-bit position data, 4-bit CRC, 4-bit status flags, and diagnostic fields. Frame period is fixed at 882 μs, with sync pulse marking frame boundaries per Figure 3 in the datasheet.
Does MLX90366LVS-ADS-250-RE support thermal output offset correction?
No, MLX90366LVS-ADS-250-RE does not support thermal output offset correction. This feature is explicitly excluded from ADS-xxx variants per Section 14.1.6 of the datasheet, which states "Thermal Output Offset correction (for AxX-xxx option code only)". MLX90366LVS-ADS-250-RE uses standard calibration without temperature-dependent offset compensation.
What is the maximum magnetic field the MLX90366LVS-ADS-250-RE can withstand?
The MLX90366LVS-ADS-250-RE supports magnetic flux densities up to ±1 T (1000 mT) per Absolute Maximum Ratings (Section 5). However, optimal performance requires BX/BY ≤70 mT and BZ ≤126 mT to avoid IMC saturation and maintain linearity, as specified in Section 9's magnetic operating conditions.
How is the 17-point LNR transfer characteristic programmed in MLX90366LVS-ADS-250-RE?
The 17-point LNR curve in MLX90366LVS-ADS-250-RE is programmed via EEPROM using dedicated address ranges defined in Section 12 (e.g., LNRAX–LNRCS for AxU-xxx, but ADS-xxx uses full 17-point memory map). Programming requires Melexis' PTM software and SENT-compatible programmer; all points are user-definable to match mechanical/magnetic system nonlinearity.
Is MLX90366LVS-ADS-250-RE pin-compatible with other MLX90366 variants in DMP-4 package?
Yes, MLX90366LVS-ADS-250-RE is pin-compatible with all MLX90366 variants in the DMP-4 package (e.g., AEV-250, AEX-250), sharing identical 4-pin layout (VSS–VDD–OUT–VSS), electrical pin functions, and mechanical footprint per Section 19.5 of the datasheet.
