STP11DF55
General Description
The STP11DF55 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, STP11DF55 is robust for all kinds of application environment.
The STP11DF55 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.
