LC82102 Datasheet, PDF (5/5 Pages) Sanyo Semicon Device – Image-Processing LSI for Fax, Copier and OCR Products

Sample Application
LC82102, LC82102W
1. C1: Use a 0.01 µF laminated ceramic capacitor.
2. Set up the polarity of the image signal from the sensor so that white data is represented by the highest potential and
black data by the lowest potential. A level conversion circuit can allow the whole dynamic range of the built-in A/D
converter to be used effectively if the maximum output level of the peaks in the image signal from the sensor does
not reach 4.2 V.
3. Although AGND and DGND are completely isolated internally in this LSI, AV_DD and DV_DD are connected through
the substrate. Therefore, the power supply system must be designed so that no potential difference between AV_DD
and DV_DD can occur. Also, when power is applied or removed, the time lag between the power supplies must be
under 3 ms.
