Two single sensing elements and two compensating elements are connected to built-in FET in
source follower circuit, connections "Drain-Source-Ground". It is recommended to use a load
resistor of 47 kΩ.
Unless specified differently, all data refer to 25°C and VDD= 11 V:
min.: 2.2 kV/W
typ.: 3.5 kV/W
Responsivity is measured within spectral range 7 - 14 µm as per fig. 3 at 1Hz.
Temperature coefficient of responsivity typ.: -0.1 %/K.
max.: 50 µVpp
typ.: 15 µVpp
After a 10 minute settling time, noise is monitored for the duration of 1500 sec. at a
temperature of 25°C, shut from infrared energy, electrical bandwidth of 0.4 to 10Hz.
VDD= 2-12 V
VS= 0.2-1.5 V
VDS= min 0.5 V
