Product Summary
The UPD3797CY is a color CCD (charge coupled device) linear image sensor which changes optical images to electrical signal and has the function of color separation. The UPD3797CY has 3 rows of 5300 pixels, and each row has a singel sided readout type of charge transfer register. And it has reset feed-through level clamp circuits, sample and hold circuits and voltage amplifiers. Therefor, it is suitable for 600 dpi/A4 color image scanners, color facsimiles and so on.
