3 COLOR CCD LINEAR IMAGE SENSOR
DESCRIPTION
The
µ
PD3768 is a high-speed and high sensitive color CCD (Charge Coupled Device) linear image sensor which
changes optical images to electrical signal and has the function of color separation.
The
µ
PD3768 has 3 rows of 7500 pixels, and it is a 2-output/color type CCD sensor with 2 rows/color of charge
transfer register, which transfers the photo signal electrons of 7500 pixels separately in odd and even pixels.
Therefore, it is suitable for 600 dpi/A3 high-speed color digital copiers, color scanners 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.
