Both of these Pyrodetector models provide two sensing elements in opposed series connection with a source-follower circuit.
The PYD 1388 (pictured above on left) is the base model Pyro in this Standard Analog Series, while the PYD 1398 (pictured above on right) is equipped with additional features such as a larger window to reduce white light sensitivity and a gate resistor for better low temperature performance. Both sensors are available in 2 EMI versions. The standard version features 1 RC-Filter at drain and source pin. For applications in strong EMI conditions (5G and antennas close to the sensor) a version with an additional RC-filtering stage is available to further reduce interference effects of electromagnetic disturbances.
