STP11DF45

The STP11DF45 infrared thermopile sensor for non-contact temperature measurement is a thermopile sensor having an output signal voltage directly proportional to the incident infrared (IR) radiation power. Thanks to the anti-electromagnetic interference design, STP11DF45 is robust for all kinds of application environment. An 3.2~4.1 um band pass filter in front of the sensor makes the device sensitive to infrared (IR) radiation which can transmits the glass-ceramic plate for induction cooker The STP11DF45 comprising a new type CMOS compatible thermopile sensor chip features good sensitivity, small temperature coefficient of sensitivity as well as high reproducibility and reliability. A high-precision thermistor reference chip is also integrated for ambient temperature compensation.
