µ PD8870
10680 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
DESCRIPTION
The µ PD8870 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 PD8870 has 3 rows of 10680 pixels, and each row has a double-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.
