DATA SHEET
MOS INTEGRATED CIRCUIT
µPD3778
10600 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
The µPD3778 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 µPD3778 has 3 rows of 10600 pixels, and each row has a double-sided readout type of charge transfer register.
And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for 1200 dpi/A4 color
image scanners and so on.
