electrical signal and has the function of color separation.
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.
