MLX90636 / Ultra-miniature infrared thermometer IC
The MLX90636 is a non-contact infrared temperature sensor in a small SMD Chip-scale package. The device is factory calibrated with calibration constants stored in the EEPROM memory. The ambient and object temperature can be calculated externally based on these calibration constants and the measurement data. The MLX90636 is highly resistant to temperature fluctuations in its environment, ensuring accurate measurements. Localized thermal variations, such as air turbulence, will not affect the thermopile's output signal. The supply voltage of the MLX90636 is either 2.8 or 3.3V. For the I2C communication with the master microcontroller, the MLX90636 supports either 1.2V, or 1.8V I2C bus voltage. An optical filter is integrated in the sensor to provide ambient light immunity. The wavelength pass band of this optical filter is from 2 till 20μm.
