[FAQ] OPT3004: OPT3001 vs OPT3004, what is the difference?

OPT3001 and OPT3004 are quite similar devices. OPT3004 is a newer part that adds better angular IR rejection. This is specifically useful in IP camera applications that use infrared LEDs and a dome shaped glass that reflects the IR light from all angles into the light sensor. Both devices are the same size and pin to pin compatible.
