Si photodiode with preamp

S8745-01

null

Photodiode and preamp integrated with feedback resistance and capacitance

This is a low-noise sensor consisting of Si photodiode, op amp, feedback resistance and capacitance, all integrated into a small package. By simply connecting to a power supply, it 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.


Features
-Use low power consumption FET input operational amplifier
-Built-in Rf=1 GΩ and Cf=5 pF
-Variable gain with an externally connected resistor
-Low noise, low NEP
-Package with shielding effect
-Highly resistance to EMC noise
