µPD8871
Color(A4)
10680 Pixels × 3 Color CCD Linear Image Sensor
Overview
The µPD8871 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 µPD8871 has 3 rows of 10680 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 1200 dpi/A4 color image scanners, color facsimiles and so on.
