LC82103 Datasheet (Sanyo Semicon Device)

LC82103, Image-Processing LSI

Ordering number : EN 5402 CMOS LSI LC82103 Image-Processing LSI for Facsimile, Copier, and OCR Applications Preliminaly Overview The LC82103 converts the analog video signal from the CCD contact image sensor into high-precision binary image data.

The LC82103 includes an 8-bit A/D converter and two 6-bit D/A converters.

The 6-bit D/A converters are used for setting reference potential (high and low) of the 8-bit A/D converter.

The LC82103 converts the input analog data to high precision mul
