μPD8821
7300 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
DESCRIPTION
The μ PD8821 is a high-speed and high sensitive color CCD (Charge Coupled Device) linear image sensor which
changes optical images to electrical signal and has the function of color separation.
The μ PD8821 has 3 rows of 7300 pixels, and it is a 2-output/color type CCD sensor with 2 rows/color of charge
transfer register, which transfers the photo signal electrons of 7300 pixels separately in odd and even pixels.
Therefore, it is suitable for 600dpi/A3 high-speed color digital copiers, color scanners and so on by the use of the
package with heat sink that has high heat radiation.
