AMIS-710250: 200dpi CIS Module
Data Sheet
Figure 1: AMIS-710250 Module Block Diagram
The PCB containing the imaging array is enclosed in a module housing, along with a one-to-one graded indexed micro lens array that
focuses the scanned documents' image onto the sensing line of the sensor chips. The document is illuminated with a LED light source
which is also mounted in the housing. See Figure 2.
Figure 2: AMIS-710250 Cross Sectional View
This pictorial cross section shows the LED bar light source and its illumination path. The light on the document reflects images on the
document. The reflected images focus through the micro lens onto the chips' image sensing line where images are converted to
proportional electrical charges. An on board amplifier processes these signal charges into proportional video signal voltages, which are
sent out to the output video port.
