S9295Si photodiode with preamp


Datasheet [231 KB/PDF]

Large area photodiode integrated with op amp and TE-cooler


THe S9295 is a thermoelectrically cooled Si photodiode with preamp developed for low-light-level detection. A large area photodiode, op amp, TE-cooler and feedback resistor (10 GΩ) are integrated into a single package. A thermistor is also included in the same package for temperature control so that the photodiode and I-V conversion circuit can be cooled for stable operation. The S9295 also features low noise and low NEP, and is especially suitable for NOx detection. The photosensitive area of the photodiode is internally connected to the GND terminal making it highly resistant to EMC noise.
