S9269, S9270
Photodiode and preamp integrated with feedback resistance and capacitance
S9269 and S9270 are low-noise photosensors consisting of a Si photodiode, op amp, and feedback resistance and capacitance, all
integrated into a ceramic package with a surface size equal to our standard ceramic packages. These photosensors are ideal for a wide
range of photometric applications including analytical equipment and measurement equipment. The active area of the photodiode is
internally connected to the GND terminal making it highly resistant to EMC noise. Combinations with various photodiodes such as UV
sensitivity enhanced type, IR sensitivity suppressed type and IR sensitivity enhanced type are also available. (Custom order products)
