10600 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR

The µPD3719 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 µPD3719 has 3 rows of 10600 pixels, and each row has a single-sided readout type of charge transfer register. It has reset feed-through level clamp circuits and voltage amplifiers. Moreover, a large dynamic range is realized by using a large saturation voltage and a low-noise amplifier. Therefore, it is suitable for 1200 dpi/A4 professional color image scanners and so on.
