DESCRIPTION
The μPD8821 is a high-speed and high sensitive color CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal and has the function of color separation. The μPD8821 has 3 rows of 7300 pixels, and it is a 2-output/color type CCD sensor with 2 rows/color of charge transfer register, which transfers the photo signal electrons of 7300 pixels separately in odd and even pixels. Therefore, it is suitable for 600dpi/A3 high-speed color digital copiers, color scanners and so on by the use of the package with heat sink thathas high heat radiation.
