DATA SHEET

MOS INTEGRATED CIRCUIT

The

µPD3798 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

µPD3798 has 3 rows of 5348 pixels, and each row has a single-sided readout type of charge transfer register.

And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for 600 dpi/A4 color

image scanners, color facsimiles and so on.
