The TCD1500C is a high sensitive and low dark current
5340-elements linear image sensor. The sensor can be
used for facsimile, imagescanner and OCR. The signal pre-
processing circuit which is composed of Sample and Hold
circuit and Pre-amplifier circuit. The device contains a row
of 5340 photodiodes, which provide a 16 lines/mm
(4OODPI) across a A3 size paper and besides 24 lines/mm
(600DPI) across a A4 size paper.

CAUTION
1. Window Glass
The dust and stain on the glass window of the package degrade optical performance of CCD
sensor.
Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the
surface, and allow the glass to dry, by blowing with filtered dry N2.
Care should be taken to avoid mechanical or thermal shock because the glass window is easily to
damage.
2. Electrostatic Breakdown
Store in shorting clip or in conductive foam to avoid electrostatic breakdown.
3. Incident Light
CCD sensor is sensitive to infrared light.
Note that infrared light component degrades resolution and PRNU of CCD sensor.
