DATA SHEET
MOS INTEGRATED CIRCUIT
µPD3788
7300 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
The µPD3788 is a high-speed and high sensitive color CCD (Charge Coupled Device) linear image sensor which
changes optical images to electrical signal and has the function of color separation.
The µPD3788 has 3 rows of 7300 pixels, and it is a 2-output/color type CCD sensor with 2 rows/color of charge
transfer register, which transfers the photo signal electrons of 7300 pixels separately in odd and even pixels.
Moreover, the spectral response characteristics of the µPD3788 is modified from the previous device µPD3728 to be
suitable for Xe-lamp. Therefore, it is suitable for 600 dpi/A3 high-speed color digital copiers and so on.
