Is common cathode connected to ground
WebJan 2, 2024 · That is the Anode will be connected towards the ground and the cathode will be connected to supply voltage. When connected in this way (shown in the circuit below) the photodiode will start conducting some current based on the light sensed by it. The maximum current that could flow during full light condition is 40μA.
