µPD8894
Color(A4)
(10680+10680) Pixels × 3 + 5340 Pixels × 3 Color CCD Linear Image Sensor
Overview
The µPD8894 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 µPD8894 has 3 rows of (10680+10680) staggered pixels, and each row has a dual-sided readout type of charge transfer register, and has 3 rows of 5340 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 2400 dpi/A4 color image scanners, color facsimiles and so on.
