DESCRIPTION
The μ PD8835 is a very high-speed color CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal and has the function of color separation. The μ PD8835 has the high speed voltage amplifiers, which have four outputs per color, and the high speed registers, so it is possible that the image of the high density is read at very high speed. Therefore, it is suitable for very high-speed 600dpi/A3 color digital copiers, color scanners and so on, by the package with heat sink that has high heat radiation.
