CCD Linear Image Sensor
MN3611RE
Color CCD Linear Image Sensor
with 720 Pixels each for R, G, and B Colors
s Overview
The MN3611RE is a high responsivity CCD color linear image
sensor having low dark output floating photodiodes in the
photodetector region, CCD analog shift registers for read out, and 720
pixels each for the primary colors R, G, and B.
It can read a B6 size color document with a high quality and a
resolution of 170dpi.
s Features
• 2160 (720 × R.G.B) floating photodiodes and an n-channel buried
type CCD shift registers are built in a single chip.
• It is possible to read a B6 size color document with a high quality
and a resolution of 170dpi.
• RGB primary colors type on chip color filters are used for color
separation.
• Very high responsivity is obtained because voltage amplifier
circuits are built in the chip.
• Use of photodiodes with a new structure has made the dark output
voltage very low.
• Large signal output of typically 2V at saturation can be obtained.
