UPD3720A

DATA SHEET MOS INTEGRATED CIRCUIT µPD3720A 2700 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR The µPD3720A 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 µPD3720A has 3 rows of 2700 pixels and 3 pairs of 2 rows of 1350-bit charge transferred registers, reset feedthrough level clamp circuits, clamp pulse generation circuit and voltage amplifiers. It is suitable for color image scanners, color facsimiles and so on.
