Product details
Overview
MLX90632SLD-DCB-100-RE from Melexis is a medical-grade far-infrared non-contact temperature sensor in a 3×3 mm SFN SMD package, delivering ±0.2°C object temperature accuracy from 35°C to 42°C, 50° field of view, I²C interface (3.3V logic), and factory-stored calibration constants for external ambient/object temperature calculation - used in clinical-grade ear and forehead thermometers.
For engineers reviewing the MLX90632SLD-DCB-100-RE datasheet, pinout, applications, or equivalent options, key selection considerations include medical-accuracy calibration range, 0.01°C measurement resolution, 16 ms–2 s configurable refresh rate, integrated long-wave IR optical filter (2–14 µm), and software-definable I²C address with ADDR pin.
Technical Context
The MLX90632SLD-DCB-100-RE implements a thermopile-based far-infrared sensing architecture with on-chip signal amplification, 16-bit ADC conversion, and digital filtering; raw pixel data and auxiliary sensor outputs are stored in 96×16-bit RAM accessible via I²C.
It integrates dual thermal compensation: one for ambient package temperature drift (measured by on-die sensor), and another for localized thermal gradients using proprietary circuitry that minimizes turbulence-induced noise and spatial thermal interference - enabling stable operation under non-isothermal PCB conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Accuracy (Object) | ±0.2°C over 35–42°C - guaranteed only under thermal equilibrium and full FOV fill, for clinical body temperature measurement. |
| Resolution | 0.01°C (medical mode) - enables sub-centigrade trend detection in fever monitoring applications. |
| Field of View | 50° - defines minimum target distance-to-diameter ratio for accurate spot measurement in compact handheld devices. |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3V LDOs; POR threshold 1.3–2.4 V ensures reliable startup across temperature. |
| I²C Interface | Fast Mode Plus (1 MHz) - supports high-speed burst reads of RAM data without interrupting measurement cycles. |
| Refresh Rate | Configurable 16 ms to 2 s - allows trade-off between responsiveness (e.g., fast screening) and power (e.g., battery-operated wearables). |
| Sleep Current | <2.5 µA - enables multi-month operation on coin-cell batteries when paired with host MCU wake-on-I²C. |
Pinout & Package
MLX90632SLD-DCB-100-RE uses a 5-pin Single Flat No-lead (SFN) package, 3.0 × 3.0 × 0.7 mm, with exposed thermal pad (non-electrical), compliant with JEDEC MO-220, and designed for reflow soldering per IPC/JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDA) | I²C bidirectional data line | Open-drain output with 10 pF capacitance; requires external pull-up to VDD; supports ACK/NACK handshake. |
| 2 (VDD) | Power supply input | Accepts 3.0–3.6 V; internal POR circuit triggers reset if voltage drops below 1.3 V during power-up. |
| 3 (GND) | Ground reference | Common return for analog and digital sections; must be low-impedance connection to minimize thermal EMF errors. |
| 4 (SCL) | I²C clock input | Input-only clock line; 10 pF max capacitance; timing compliant with Fast Mode Plus (1 MHz) specification. |
| 5 (ADDR) | I²C address LSB control | Logic level sets slave address: grounded = 0x3A (default), pulled high = 0x3B; leakage <1 µA ensures minimal current draw. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-calibrated medical accuracy | Delivers ±0.2°C object temperature error over 35–42°C without user calibration - reduces firmware development time and regulatory validation burden. |
| Integrated long-wave IR optical filter | 2–14 µm spectral bandpass eliminates visible and NIR interference - enables reliable operation under ambient lighting, sunlight, or LED illumination. |
| Thermal gradient immunity | On-die compensation circuits reject localized heating/cooling effects from adjacent components - maintains accuracy on densely populated PCBs. |
| Software-configurable I²C address | Single ADDR pin toggles between two addresses (0x3A/0x3B) - simplifies multi-sensor systems without requiring external address jumpers or EEPROM writes. |
| Extended range measurement mode | Supports object temperatures from –20°C to +100°C in medical configuration - enables dual-use in both clinical and industrial monitoring applications. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-contact infrared temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90632SLD-BCB-100-RE | Standard accuracy version: ±1.0°C over –20°C to +200°C object range; no medical calibration constants. | Targeted at industrial process control, not clinical diagnostics; lacks FDA-aligned accuracy spec. | Select when cost sensitivity outweighs medical-grade precision and wider object temperature range is required. |
| AMG8833 | 8×8 thermal array (64 pixels); 0.25°C resolution; no factory calibration; requires external optics and complex NUC compensation. | Used for thermal imaging and gesture recognition - not single-point clinical thermometry. | Choose only if spatial temperature mapping is needed; adds significant firmware overhead and optical design complexity. |
Compared with MLX90632SLD-DCB-100-RE, the standard MLX90632SLD-BCB-100-RE trades medical accuracy for broader industrial range, while AMG8833 provides imaging capability at the expense of calibration simplicity, power efficiency, and single-point measurement reliability.

FAQ
What distinguishes MLX90632SLD-DCB-100-RE from standard MLX90632 variants?
The MLX90632SLD-DCB-100-RE is the medical-accuracy variant: it features factory calibration to ±0.2°C over 35–42°C, 0.01°C resolution, and extended range mode (–20°C to +100°C). Its "D" option code denotes medical accuracy, "C" indicates high-stability version, "B" specifies 50° FOV, and "100" confirms 3.3V I²C logic - all verified in Melexis' official ordering guide and datasheet revision 13.
Does MLX90632SLD-DCB-100-RE require external calibration for clinical use?
No, MLX90632SLD-DCB-100-RE is fully factory-calibrated with trimming values and calibration constants stored in on-chip EEPROM. Clinical accuracy (±0.2°C) is achieved directly from external temperature calculation using those constants - no user calibration is needed, though optical window compensation can be applied in firmware if required.
How does the MLX90632SLD-DCB-100-RE handle thermal interference from nearby PCB components?
The MLX90632SLD-DCB-100-RE integrates dedicated thermal compensation circuits that monitor package temperature gradients and suppress noise from hot electronics or adjacent heaters. This design minimizes measurement drift caused by localized thermal variations - a key differentiator confirmed in Section 2 ("Description") and Figure 3 ("Block diagram") of the datasheet.
What is the function of the ADDR pin on MLX90632SLD-DCB-100-RE?
The ADDR pin on MLX90632SLD-DCB-100-RE sets the LSB of the I²C slave address: grounded = 0x3A (default), pulled high = 0x3B. This enables two MLX90632SLD-DCB-100-RE sensors on the same bus without address conflict - a hardware-level configuration confirmed in Table 5 ("Pin definitions") and Section 9.1 ("I2C address").
Can MLX90632SLD-DCB-100-RE operate with 1.8V I²C logic levels?
No, MLX90632SLD-DCB-100-RE is the 3.3V I²C version (indicated by "100" in the option code: "1" = 3.3V, "0" = 1.8V). The "100" suffix explicitly denotes 3.3V I²C compatibility; 1.8V variants use "110" or "010" codes and are separate orderables - per Table 2 ("Coding legend") and Ordering Information section.
