Product details
Overview
MLX90614ESF-BBA-000-SP from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 package, delivering ±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 HVAC and medical-grade monitoring systems.
For engineers reviewing the MLX90614ESF-BBA-000-SP datasheet, pinout, applications, or equivalent options, key selection factors include its 3.0V supply operation, -40°C to +85°C ambient rating, integrated optical long-wave pass filter (5.5–14 µm), 10-bit PWM output with 0.14°C resolution, and thermal gradient compensation capability in xCx variants.
Technical Context
The MLX90614ESF-BBA-000-SP integrates a thermopile detector and signal-conditioning ASSP in one TO-39 can, using a low-noise chopper amplifier, 17-bit ADC, and DSP-based computation to derive ambient (Ta) and object (To) temperatures. Its internal FIR/IIR filtering enables configurable refresh rates and noise performance.
It operates as an SMBus slave device (default address 0x5A) with programmable EEPROM registers for emissivity (0.1–1.0), PWM range, and thermal relay thresholds. The BBA variant uses 3.0V supply, supports sleep mode (2–6 µA), and excludes zener protection on SCL - distinguishing it from Axx versions.

Pinout & Package
MLX90614ESF-BBA-000-SP is housed in an industry-standard 4-pin TO-39 metal can package with hermetically sealed IR window and internal optical filter. Pin 1 (SCL/Vz) functions as SMBus clock input only (no zener - Bxx variant); Pin 2 (SDA/PWM) serves as bidirectional data line or PWM output; Pins 3 and 4 are dedicated to VDD and VSS respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SCL input | SMBus serial clock - no internal zener diode (Bxx variant), requires external pull-up |
| 2 | SDA I/O or PWM output | Configurable bidirectional data line or open-drain/push-pull thermal relay output |
| 3 | VDD supply | 3.0 V nominal input - supports 2.6–3.6 V operation; no high-voltage adaptation needed |
| 4 | VSS ground | Reference node for all signals - metal can must connect *only* to this pin per EMC/isothermal requirements |
Key Features
| Feature | Design Value |
|---|---|
| Factory calibration | Pre-programmed Ta/To coefficients and emissivity (ε = 1.0) stored in EEPROM - eliminates field calibration effort |
| Thermal gradient compensation | Internal measurement and correction for package ΔT - improves accuracy in non-isothermal mounting conditions |
| User-programmable PWM | Two EEPROM registers define custom To range (-20°C to +120°C default) - enables direct mapping to control logic without host MCU scaling |
| Thermal relay mode | PWM pin reconfigured as programmable threshold alert - implements hardware-level freeze/boil detection without firmware polling |
| Medical-grade accuracy option | ±0.2°C at 36°C–37°C (available in specific variants) - meets clinical thermometer requirements when configured |

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 |
|---|---|---|---|
| MLX90614ESF-BCI-000-SP | Same TO-39 package and 3.0V supply, but features uncoated silicon lens (no long-wave pass filter) - wider spectral response (1–20 µm) | Lacks sunlight/ambient immunity - suitable only for controlled indoor environments with known emissivity targets | Select only when measuring low-emissivity metals or requiring extended spectral sensitivity beyond 14 µm |
| AMG8833 | 8×8 thermal array (64 pixels) vs. single-point MLX90614; I²C interface only; no PWM; lower accuracy (±2.5°C) | Enables thermal imaging and motion detection - not a drop-in replacement for spot temperature measurement | Choose for presence detection or spatial temperature profiling; avoid when single-point precision or hardware alerting is required |
Compared with MLX90614ESF-BBA-000-SP, the BCI variant trades ambient immunity for broader spectral coverage, while the AMG8833 shifts from precision spot sensing to low-resolution thermal imaging - neither offers pin compatibility or identical SMBus register mapping.

FAQ
What is the operating voltage range for MLX90614ESF-BBA-000-SP?
The MLX90614ESF-BBA-000-SP operates from 2.6 V to 3.6 V, making it compatible with standard 3.0 V systems including battery-powered devices. It does not support 5 V or higher supply voltages - unlike the Axx series - and lacks the internal zener diode on the SCL pin. This voltage range ensures low-power operation while maintaining full functionality of SMBus communication and PWM output.
Does MLX90614ESF-BBA-000-SP support sleep mode?
Yes, MLX90614ESF-BBA-000-SP supports sleep mode with typical current consumption of 2–6 µA, enabled via SMBus command. This feature is exclusive to Bxx and Dxx variants (3.0 V supply) and is unavailable in Axx (5.0 V) versions. Sleep mode reduces power between measurements without losing calibration or configuration settings stored in EEPROM, making it ideal for portable thermal monitors and energy-sensitive IoT nodes.
Can MLX90614ESF-BBA-000-SP measure human body temperature accurately?
Yes, MLX90614ESF-BBA-000-SP achieves ±0.5°C accuracy from 0°C to +50°C - sufficient for general wellness screening. For clinical-grade use, Melexis offers a medical-accuracy variant (±0.2°C at 36°C–37°C) with tighter calibration; the BBA-000-SP itself is not certified to that level but can be configured with appropriate optics, distance-to-target ratio, and emissivity (ε ≈ 0.97–0.98) to meet basic regulatory requirements in Class II medical devices.
How is emissivity adjusted on MLX90614ESF-BBA-000-SP?
Emissivity is adjusted by writing a 16-bit value to EEPROM address 0x04, where decimal 65535 corresponds to ε = 1.0. The formula is dec2hex[round(65535 × ε)], supporting values from 0.1 to 1.0. This write requires SMBus access and an erase cycle prior to programming. Once set, the value persists across power cycles and affects all subsequent To calculations - enabling accurate readings on non-blackbody surfaces like skin, plastic, or painted metal without external compensation.
What is the default communication interface for MLX90614ESF-BBA-000-SP at power-on?
The MLX90614ESF-BBA-000-SP defaults to SMBus mode at power-on reset (POR), with slave address 0x5A. The PWM function is disabled until explicitly enabled via EEPROM configuration register (address 0x02). This ensures reliable initialization in multi-device SMBus systems and avoids bus contention. The transition between interfaces is software-controlled and does not require hardware reconfiguration or pin strapping.
