Si photodiodes with preamp
S8745-01 S8746-01
Photodiode and preamp integrated with
feedback resistance and capacitance
The S8745-01 and S8746-01 are low-noise sensors consisting of Si photodiode, op amp, and feedback resistance and ca-
pacitance, all integrated into a small package. By simply connecting to a power supply, the S8745-01 and 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.
