PHOTODIODE
Si photodiode with preamp
Photodiode and preamp integrated with feedback resistance and capacitance
S8745-01, S8746-01
S8745-01, S8746-01 are low-noise sensors consisting of Si photodiode, op amp, and feedback resistance and capacitance, all integrated into a
small package. By simply connecting to a power supply, S8745-01 and S8746-01 can be used in low-light-level measurement such as 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.
