DESCRIPTION
The
µ
PD8862 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
PD8862 has 3 rows of (2700 + 2700) 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 amplifiers. Therefore, it is suitable for
600 dpi/A4 color image scanners, color facsimiles and so on.

Note
Use at the condition without dew condensation.
Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.
