DATA SHEET
MOS INTEGRATED CIRCUIT
μ PD8884A
(10680 PIXELS × 4 LINES) × 3 COLOR CCD LINEAR IMAGE SENSOR
DESCRIPTION
The μ PD8884A 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 PD8884A has 3 rows of (10680 × 4) staggered pixels, and each row has a dual-sided readout-type charge
transfer register. And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for
4800 dpi/A4 color image scanners.
