Product details
Overview
MLX90614ESF-ACF-000-SP from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 metal can package, delivering ±0.5°C accuracy (0°C to +50°C) for both ambient and object temperature, 0.02°C measurement resolution in SMBus mode, and dual-output capability via SMBus interface and configurable PWM. It serves as a non-contact thermal sensing element in automotive HVAC, medical thermometry, and industrial temperature monitoring systems.
For engineers reviewing the MLX90614ESF-ACF-000-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its -40°C to +85°C ambient operating range, 5.0V supply compatibility, SMBus slave address 0x5A, integrated optical long-wave pass filter (5.5–14 µm), and thermal gradient compensation in Cx variants - though this specific ACF variant uses standard calibration without internal gradient correction.
Technical Context
The MLX90614ESF-ACF-000-SP integrates a thermopile IR detector and signal-conditioning ASSP on a single die inside a hermetically sealed TO-39 can. Its architecture includes a low-noise chopper amplifier, 17-bit sigma-delta ADC, and dedicated DSP engine enabling real-time computation of ambient (Ta) and object (To) temperatures with 0.01°C internal resolution.
It supports two communication modes: SMBus (default power-on reset setting) with 10–100 kHz clock, and user-configurable 10-bit PWM output with 1.024 ms period and ±10% stability over temperature and supply. The device implements EEPROM-based configuration for emissivity (0.1–1.0), temperature ranges, and PWM scaling - all programmable without black-body recalibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Ambient Temp Range | -40°C to +85°C - defines maximum allowable sensor housing temperature during operation |
| Object Temp Range | -70°C to +380°C - usable field-of-view target temperature span before saturation |
| Accuracy (Ta/To) | ±0.5°C at 0°C to +50°C - guaranteed error bound under isothermal conditions |
| Resolution (SMBus) | 0.02°C - smallest distinguishable temperature step in digital register reads |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5V logic rails and tolerant of ±5% variation |
| Current Consumption | 1.3 mA typical - enables continuous operation in low-power embedded systems |
| SMBus Address | 0x5A (7-bit) - fixed slave address simplifies multi-device bus topology design |
| Optical Filter Band | 5.5 µm to 14 µm - blocks visible/NIR light, ensuring immunity to ambient sunlight and incandescent sources |
Pinout & Package
MLX90614ESF-ACF-000-SP is housed in an industry-standard 4-pin TO-39 metal can package with hermetic sealing and integrated long-wave infrared optical filter. The metal case is electrically connected only to Pin 4 (VSS) per EMC and isothermal best practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL / Vz | SMBus clock input / Zener clamp | Accepts 10–100 kHz SMBus clock; internal 5.7 V zener protects against overvoltage on 5V versions |
| 2: SDA / PWM | Bi-directional data / PWM output | Default SMBus data line; reconfigurable as open-drain or push-pull PWM output for analog-like temperature reporting |
| 3: VDD | Positive supply | 4.5–5.5 V DC input; powers internal regulator, ADC, DSP, and interface logic |
| 4: VSS | Ground reference | System ground return; sole electrical connection point to metal can for thermal and EMI stability |
Key Features
| Feature | Design Value |
|---|---|
| Factory calibration | Delivers traceable Ta/To readings across full -40°C to +85°C ambient and -70°C to +380°C object ranges without end-user calibration |
| Configurable PWM output | 10-bit free-running output with user-defined temperature range and resolution (e.g., -20°C to +120°C @ 0.14°C step) |
| Thermal relay mode | PWM pin reprogrammable as comparator output with user-set threshold for thermostat or freeze-alert functions |
| Emissivity adjustment | EEPROM-stored 16-bit emissivity value (0.1–1.0) enables accurate readings on non-blackbody surfaces without hardware changes |
| High-voltage adaptation | Supports 8–16 V operation using external resistor-zener network - eliminates need for separate 5V regulator in automotive 12V systems |

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 |
|---|---|---|---|
| MLX90614ESF-BCC-000-TU | 3.0 V supply (2.6–3.6 V), 2–6 µA sleep current; no internal zener on SCL | Battery-powered or ultra-low-power designs where 5V rail unavailable | Select when system operates from 3V battery or regulated supply and requires sleep mode - MLX90614ESF-ACF-000-SP lacks sleep functionality. |
| MLX90614KSF-ACC-000-TU | Extended ambient range (-40°C to +125°C); identical 5V supply and SMBus/PWM interface | Under-hood automotive, industrial enclosures, or high-ambient environments | Select when ambient temperature exceeds +85°C - MLX90614ESF-ACF-000-SP is rated only to +85°C ambient. |
Compared with MLX90614ESF-BCC-000-TU and MLX90614KSF-ACC-000-TU, the MLX90614ESF-ACF-000-SP offers optimal balance of 5V compatibility, medical-grade resolution, and cost-effective integration for commercial HVAC and appliance applications within its -40°C to +85°C ambient envelope.

FAQ
What is the operating temperature range for the MLX90614ESF-ACF-000-SP?
The MLX90614ESF-ACF-000-SP has an ambient operating temperature range of -40°C to +85°C and measures object temperatures from -70°C to +380°C. This makes it suitable for commercial and light-industrial environments but not for under-hood automotive use, which requires the KSF variant rated to +125°C ambient. The device must be mounted in isothermal conditions to maintain its ±0.5°C accuracy specification.
Does the MLX90614ESF-ACF-000-SP support sleep mode?
No, the MLX90614ESF-ACF-000-SP does not support sleep mode. Sleep mode is only available on the 3.0 V supply variants (e.g., MLX90614Bxx), which achieve 2–6 µA quiescent current. The MLX90614ESF-ACF-000-SP draws 1.3–2.5 mA continuously and is intended for always-on applications such as HVAC feedback loops or appliance safety monitoring.
How is emissivity configured on the MLX90614ESF-ACF-000-SP?
Emissivity is stored in EEPROM address 0x04 as a 16-bit value representing ε × 65535 (e.g., 0xFFFF = 1.0). It can be written via SMBus without black-body recalibration and supports values from 0.1 to 1.0. The MLX90614ESF-ACF-000-SP defaults to ε = 1.0 at power-up, and changes persist across power cycles due to 10-year EEPROM data retention at 85°C.
Can the MLX90614ESF-ACF-000-SP operate from a 12V supply?
Yes - the MLX90614ESF-ACF-000-SP (5V version) can operate from 8–16 V using an external resistor-zener network to regulate down to 5V. Section 5.5 of the datasheet provides the exact circuit: a series resistor and 5.7 V zener diode (connected to SCL/Vz pin) drop excess voltage while maintaining stable VDD. This avoids needing a separate 5V LDO in 12V automotive or industrial systems.
What is the default communication interface for the MLX90614ESF-ACF-000-SP at power-up?
The MLX90614ESF-ACF-000-SP powers up in SMBus mode by default, with slave address 0x5A (7-bit). The SDA/SCL pins function as open-drain bidirectional SMBus lines. PWM mode must be explicitly enabled via EEPROM configuration (PWMCTRL register) and requires a POR cycle to activate - it is not active out-of-box.
