S8746-01Si photodiode with preamp


Datasheet [218 KB/PDF]

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.
