µPD8891
Color(A4)
(5340+5340) Pixels × 3 + 2670 Pixels × 3 Color CCD Linear Image Sensor
Overview
The µPD8891 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 µPD8891 has 3 rows of (5340+5340) staggered pixels, and each row has a dual-sided readout type of charge transfer register, and has 3 rows of 2670 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.
