AMIS-710214: 200dpi Two Level Digital Output Module
Data Sheet
The AMIS-710214 module consists of 27 sensors that are cascaded to provide 1728 photo-detectors with their associated multiplex
switches and a digital shift register that controls its sequential readout. Mounted in the module is a one-to-one graded-indexed micro
lens array that focuses the scanned documents to image onto its sensing plane. A buffer amplifier amplifies the video pixels from the
image sensors and passes them to analog digitizing circuit, where video pixels are converted to digital signal and passed to output of
the module. See Figure 1.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing, which
has a cover glass, which acts as the focal point for the object being scanned and protects the imaging array, micro lens assembly and
LED light source from dust. The pictorial of AMIS-710214 cross section is shown in Figure 2.

I/O to the module is a 2 x 2mm 16-pin unshrouded connector (see I/O pin assignment, under Specifications) located on one end of the
module (see module drawing).
