Si photodiode with preamp
S8745-01
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
