3 COLOR CCD LINEAR IMAGE SENSOR
DESCRIPTION
The
μ
PD8882 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
PD8882 has 3 rows of (10680 + 10680) 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
2400 dpi/A4 color image scanners.
