YK-PD53NL 400-1100nm Transimpedance Photoelectricity Detector 4-Level Gain Adjustable High Speed Photodetector

Description:
- YK-PD53NL is a high-speed and high bandwidth photodetector with a gain coefficient that can be adjusted in four levels within the range of 1-1000KV/A. The circuit gain bandwidth is greater than 20MHz, and it has the characteristics of extremely high bandwidth and low bias current. Compatible and adaptable to the vast majority of high-speed photodiode PDs. The low ripple precision power supply paired with the detector ensures excellent noise performance of the amplifier within a bandwidth of 20MHz. Usually used in pulse light conversion, laser ranging, high-speed photoelectric detection, and fluorescent substance detection.

FAQ:
Q: Why is there almost no response to the output after corresponding light irradiation?
A: Firstly, it is necessary to confirm how much light power is received by the sensor, and the photoelectric tube will form a corresponding current size. Based on the current size, the output voltage can be calculated. If the light power is too small, the output will have almost no response.

Q: Why is there a lot of noise in the input current signal and output voltage?
A: Firstly, you should use the matching wires for wiring and measurement. The input wires should not be too long or unshielded, as this can easily introduce external noise. The input current circuit should be as short and shielded as possible.
