5000 PIXELS CCD LINEAR IMAGE SENSOR
The µPD3739 is a CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical
signal.
The µPD3739 is a 2-output type CCD sensor with 2 rows of high-speed charge transfer register, which transfers
the photo signal electrons of 5000 pixels separately in odd and even pixels. It is developed as the higher sensitivity
version of the previous device, the µPD35H71A. It is suitable for 400 dpi/A3 high-speed digital copiers, OCRs and
high-end business facsimiles.
