Product Summary
The UPD3728D 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 UPD3728D 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, the UPD3728D is suitable for 600 dpi/A3 high-speed color digital copiers and so on.
