μ
PD3794
MOS INTEGRATED CIRCUIT
The
μ
PD3794 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
PD3794 has 3 rows of 2700 pixels, and each row has a single-sided readout type of charge transfer register.
And it has reset feed-through level clamp circuits, a clamp pulse generation circuit, an RGB selector and voltage
amplifiers. Therefore, it is suitable for 300 dpi/A4 color image scanners, color facsimiles and so on.
