Checked: Date: 09.11.10 Customer approval: Detector type : PYS 3228 TC G7.4/G20 Date of Issue: 13.01.09 Part no.: 3830 Date of Rev.: Date: Page: 1 Of :6 Electrical Configuration: 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. Electrical data: Unless specified differently, all data refer to 25°C and VDD= 11 V: Responsivity: 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. Noise: 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. Operating voltage: VDD= 2-12 ...
