5000-BIT × 3 CCD COLOR LINEAR IMAGE SENSOR

The µPD3725A is a high sensitivity 5000-bit × 3 CCD (Charge Coupled Device) color linear image sensor which changes optical images to electrical signal and has the function of color separation.

The µPD3725A has 3 rows of 5000-bit photocell array and 6 rows of 2500-bit charge transferred register, so it is suitable for high resolution color image scanners and digital color copiers.
