ANALOG INFRARED THERMOPILES TEMPERATURE SENSORS /// ANALOG INFRARED THERMOPILES JAN/2021 Page 2 Absolute Maximum Ratings Absolute maximum ratings are limiting values of operation and storage. They should not be exceeded initially or during operation. If exceeded, instantaneous catastrophic failure can occur. Even if the device continues to operate satisfactorily, service life may be considerably shortened.

ANALOG INFRARED THERMOPILES TEMPERATURE SENSORS /// ANALOG INFRARED THERMOPILES JAN/2021 Page 10 Field of View The thermopile’s field of view must be directed to the object surface of interest. The distance to the surface or the surface diameter must be adjusted to ensure that the complete sensors field of view is covered by the object, see example on the left in the picture below.

ANALOG INFRARED THERMOPILES TEMPERATURE SENSORS /// ANALOG INFRARED THERMOPILES JAN/2021 Page 11 Direct Sunlight Sun light radiation which is transmitted through a glass window may influence the measurement accuracy. To avoid this, the thermopile sensor is equipped with a long wavelength filter. Due to not ideal filter characteristics a small portion of radiation will be added to the radiation of the object. Touching the Sensors Cap User should avoid touching the sensors cap. There will still be a measurement deviation after changing the sensors temperature rapidly. Emissivity Every object is transmitting infrared energy that is dependent to its temperature. The emissivity is the ratio of the radiated power by an object to the radiation of an ideal black body. Common materials like liquids, clothes, human skin, foods have emissivity factors >0.90 and therefore they can be measured very accurately without altering the sensors specification. For accurate measurements the correct emissivity of the object has to be taken into account.

ANALOG INFRARED THERMOPILES TEMPERATURE SENSORS /// ANALOG INFRARED THERMOPILES JAN/2021 Page 12 Circuit Examples These circuits illustrate simple ways to interface directly to the thermopile and reference temperature sensor outputs. Additional signal processing and circuitry are required to provide an accurate temperature measurement of the target surface. A complete discussion and examples of this additional signal processing are shown in the application notes referenced on the last page of this data sheet. Interface to NTC Referenced Thermopile Interface to RTD Referenced Thermopile Due to the very low output voltage levels of thermopiles (µV to mV), the op-amp should have low input offset voltage, low drift, low input bias and leakage current, and low noise performance. Calibration of the internal temperature reference is required to obtain the best overall system accuracy.
