MOS INTEGRATED CIRCUIT
µPD3720A
2700 PIXELS Ã 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 feed-
through level clamp circuits, clamp pulse generation circuit and voltage amplifiers. It is suitable for color image
scanners, color facsimiles and so on.
