Introduce
The 8M2404-2 photodetector preamplifier is composed of an avalanche photodiode (APD) and a low noise preamplifier circuit. The product has the characteristics of low noise, high response, low power consumption and controllable gain.
Gain control: when the control voltage is 12±1.2V, the control attenuation factor is 15±3 times; When the control voltage is 0V, the control attenuation factor is 0 times.
