MOS INTEGRATED CIRCUIT
(5340 × 5340) PIXELS × 3 + 2670 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
The µ PD8891 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 µ PD8891 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.
