PHOTOREFLECTOR
Photoreflector
P7816
Thin package, photo IC diode output type photoreflector
P7816 is a photoreflector using a photo IC diode on the output. The photo IC diode consists of a photodiode integrated with a current amplifier,
and linearly amplifies and outputs the photocurrent generated in the photodiode. The two lead, current output allows operation just the same as
operating photodiodes with a reverse bias.
