MN3674

www.DataSheet4U.com CCD Linear Image Sensor MN3674 Color CCD Linear Image Sensor with 512 Pixels for R and B Colors/1024 Pixels for G Color s Overview The MN3674 is a high responsivity CCD color linear image sensor with 512 pixels each for R and B and 1024 G pixels, and having low dark output floating photodiodes in the photodetector region and CCD analog shift registers for read out. It can read a 64mm-width color document with a high quality and a maximum pseudo resolution of 400dpi. In addition to being used as a color sensor, this device can also be used as a black and white sensor if only the G row is used, and in this case, it is possible to read a 64mm-width document with a full resolution of 400dpi. Since a one line delay analog memory is built in so as to compensate for the difference in the positions of reading out between the R, B rows and the G row, the configuration of the signal processing circuit becomes simpler. s Pin Assignments 1 NC NC OS1 DS1 VSS øR ø1 ø SG1 VSS VSS NC 1 2 3 4 5 6 7 8 9 10 11 1024 (Top View) C26 22 21 20 19 18 17 16 15 14 13 12 NC NC OS 2 DS 2 VDD NC ø2 ø SG2 øV NC NC s Features 2048 floating photodiodes and n-channel buried type CCD shift registers for read out are integrated in a single chip. RGB primary colors type on chip color filters are used for color separation. In order to compensate for the distance between the photodiode rows for the R, B colors and the G color, the device has a built in analog memory that can store ...
