Si photodiode with preamp



Photodiode and preamp integrated with feedback resistance and capacitance

The S8746-01 is a low-noise sensor consisting of Si photodiode, op amp, and feedback resistance and capacitance, all integrated into a small package. By simply connecting to a power supply, The S8746-01 can be used in low-light-level measurement such as analytical equipment and measurement equipment. The photosensitive area of the photodiode is internally connected to the GND terminal making it highly resistant to EMC noise.

-Si photodiode for UV to near IR precision photometry
-Small metal package with quartz window: TO-8
-Photosensitive area: 5.8 × 5.8 mm
-FET input operational amplifier with low power dissipation
-Built-in Rf=1 GΩ and Cf=5 pF
-Variable gain with an externally connected resistor
-Low noise and NEP
-Package with shielding effect
