HI all,
i'm currently working with IR sensor diodes, and trying to find a proper device for my project, however i haven't found a good unit which fills my needs. Now that i have extended my search to phototransistors, i wonder are they compatible with photodiodes?
Im using Atmel's IR-amplifier IC and the datasheet only suggest of using photodiodes, as the IC have only 2 input pins for diode. But can i also use phototransistors?, they have 3 pins, so how should i connect them to device which only have two input pins for diode?
Im thinking that, if the IR light represents as a base control "current" then i should use collector-emitter to be as a anode-kathode in diode, am i right?
