Using a APD (Avalanche Photo Diode). See attached datasheet.
The spec sheet provides pretty good insight into how the IC works but I still have a few questions that I need help with answering.
1) What type of signal does this IC receive. Infra Red?
2)The spec says that the output is in the form of differential voltage pulsed signals. What does this actually mean? Mirror images of the signal, Like a +1v and a-1V? Why create differential signals?
3)The spec says that IC needs positive bias voltage? What does this actually mean? How do you create a bias voltage? Why does one have to generate bias voltage in the first place?
Please advise.
