Product details
Overview
MLX90614ESF-ACC-000-SP from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 metal can package, integrating thermopile detector and signal-conditioning ASSP. It delivers ±0.5°C accuracy (0°C to +50°C), -70°C to +380°C object temperature range, and SMBus/PWM dual-output interface for non-contact thermal sensing in automotive and industrial systems.
For engineers reviewing the MLX90614ESF-ACC-000-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its 5V supply compatibility, medical-grade accuracy option, thermal gradient compensation capability (via xCx variant logic), and SMBus slave address 0x5A configuration.
Technical Context
The MLX90614ESF-ACC-000-SP implements a chopper-stabilized low-noise amplifier, 17-bit sigma-delta ADC, and on-chip DSP to compute ambient (Ta) and object (To) temperatures with 0.01°C internal resolution. Its signal chain supports programmable FIR/IIR filtering and EEPROM-configurable emissivity (0.1–1.0) without black-body recalibration.
It operates as an SMBus slave device with fixed 0x5A address, supports 10–100 kHz clock frequency, and features a free-running 10-bit PWM output (default period 1.024 ms, resolution 0.14°C over –20°C to +120°C). Sleep mode is unavailable in this Axx (5V) variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5V microcontroller I/O and industrial power rails |
| Object Temp Range | –70°C to +380°C - enables high-temp industrial monitoring and low-temp cryogenic detection |
| Ambient Temp Range | –40°C to +85°C - rated for under-hood automotive and residential HVAC environments |
| Accuracy (Ta/To) | ±0.5°C at 0°C to +50°C - meets medical and precision comfort control requirements |
| Output Interface | SMBus (slave addr 0x5A) + configurable PWM - dual-mode flexibility for bus-constrained or low-pin-count designs |
| Current Consumption | 1.3 mA typical - suitable for always-on thermal monitoring with minimal power impact |
| Resolution (SMBus) | 0.02°C - enables fine-grained thermal trending and closed-loop control |
Pinout & Package
MLX90614ESF-ACC-000-SP uses the industry-standard 4-pin TO-39 metal can package with hermetically sealed IR window. The metal case must connect only to VSS (pin 4) to maintain isothermal conditions and measurement integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL / Vz | SMBus clock input / 5.7V zener clamp | Accepts 10–100 kHz SMBus clock; integrated zener protects against overvoltage on 5V systems |
| 2: SDA / PWM | Open-drain bidirectional data / PWM output | Configurable as SMBus data line or 10-bit PWM output; supports thermal relay mode |
| 3: VDD | Positive supply input | 4.5–5.5 V nominal; no sleep mode support in this Axx variant |
| 4: VSS | Ground reference | Single-point connection point for metal can; critical for thermal equilibrium and accuracy |
Key Features
| Feature | Design Value |
|---|---|
| Factory calibration | Pre-programmed Ta/To coefficients and emissivity = 1.0 enable immediate deployment without system-level calibration |
| Thermal gradient compensation | Internal thermal gradient sensing (xCx architecture) reduces measurement error from PCB hotspots or nearby heaters |
| Configurable PWM output | User-defined temperature range and duty cycle via EEPROM (addresses 0x00–0x01) preserves factory calibration integrity |
| Optical filter integration | 5.5 µm–14 µm long-wave pass filter blocks visible/NIR light, ensuring immunity to ambient sunlight and LED interference |
| EEPROM programmability | Customer-writable registers for emissivity, Ta/To range limits, SMBus address LSB, and PWM control enable field customization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-contact IR temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90614KSF-ACC-000-TU | Extended ambient operating range: –40°C to +125°C vs. –40°C to +85°C | Required for under-hood automotive or high-ambient industrial enclosures | Select when ambient temperature exceeds +85°C; identical pinout, SMBus interface, and calibration methodology |
| AMG8833 | 8×8 thermal array (64 pixels) vs. single-point measurement; I²C interface; no integrated optical filter | Enables thermal imaging and motion mapping, not spot temperature | Choose for gesture recognition or spatial heat distribution analysis; requires external optics and higher MCU processing overhead |
Compared with MLX90614KSF-ACC-000-TU, the MLX90614ESF-ACC-000-SP trades ambient temperature headroom for cost and footprint efficiency in cabin or indoor applications; versus AMG8833, it offers superior single-point accuracy, lower power, and plug-and-play optical performance without lens alignment.

FAQ
What is the operating voltage range for MLX90614ESF-ACC-000-SP?
The MLX90614ESF-ACC-000-SP operates from 4.5 V to 5.5 V DC. It belongs to the Axx (5V-compatible) family and does not support sleep mode. For 8–16 V applications, external components such as a Zener diode and resistor network are required per the datasheet's "High Voltage Operation" section. The integrated 5.7 V zener on pin 1 (SCL/Vz) provides overvoltage protection but is not intended for primary regulation.
Does MLX90614ESF-ACC-000-SP support medical-grade accuracy?
Yes, the MLX90614ESF-ACC-000-SP supports medical-grade accuracy of ±0.2°C in the human body temperature range (approximately 35°C to 42°C) when configured in the high-accuracy mode specified in the datasheet. This mode is enabled via EEPROM register settings and requires proper thermal mounting to minimize package gradients. Factory calibration covers both standard (±0.5°C) and medical accuracy profiles.
How is the SMBus address configured for MLX90614ESF-ACC-000-SP?
The MLX90614ESF-ACC-000-SP has a fixed SMBus slave address of 0x5A (7-bit address). The least significant bit of the address is stored in EEPROM register 0x0E and can be modified to support multiple devices on the same bus, though default operation assumes 0x5A. No external address pins exist - all addressing is software-configurable via the SMBus interface after power-up.
Can MLX90614ESF-ACC-000-SP measure temperature through glass or plastic?
No - the MLX90614ESF-ACC-000-SP cannot reliably measure object temperature through standard glass or acrylic due to strong absorption in the 5.5–14 µm IR band. Its integrated long-wave pass filter is optimized for direct line-of-sight measurement. For enclosure-integrated use, only IR-transparent materials like polyethylene or specialized germanium windows are suitable, and optical path length and emissivity corrections must be applied.
What is the meaning of 'ACC' in MLX90614ESF-ACC-000-SP?
In MLX90614ESF-ACC-000-SP, 'ACC' denotes the supply voltage (A = 5.0 V), gradient compensation (C = thermal gradient compensation enabled), and field-of-view (C = 35°). This confirms the device includes internal thermal gradient sensing logic (xCx architecture) and ships with a 35° half-angle optical lens, making it suitable for applications where localized thermal sources must be distinguished from background radiation.
