Description

The μPD795 is a CCD (charge-coupled device) linear image sensor that changes optical images to electrical signals. It has 1024 photo-elements, two lines of 525-bit CCD charge transfer registers, a drive unit, a sample-and-hold circuit, and an output amplifier. The drive unit simplifiers the external circuit and reduces total drive power. The sample-and-hold circuit substantially reduce output signal noise.
