UPD8872 - NEC

UPD8872 CCD LINEAR IMAGE SENSOR

The µ PD8872 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 PD8872 has 3 rows of (5400 + 5400) staggered pixels, and each row has a dual-sided readout-type charge transfer register. And it has reset feed-through level clamp circuits and voltage ampli.
