AMIS-710322-A4: 300dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710322-A4 (PI322MC-A4) is a contact image sensor (CIS) module, which uses MOS image sensor technology for high-
speed performance and high sensitivity. The AMIS-710322-A4 is suitable for scanning A4 size (216mm) documents with 11.8 dots per
millimeter (dpm) resolution. Applications include fax machines, game systems, a variety of mark readers, and other automation
equipment requiring document scanners.
2.0 Key Features
• Light source, lens and sensor are integrated into a single module
• 11.8dpm resolution, 216mm scanning length
• Up to 500µsec/line scanning speed with optional light source
• Wide dynamic range
• Analog output
• Yellow-green LED light source
• Compact size ≅ 14mm x 19.5mm x 232mm
• Low power
• Light weight
3.0 Functional Description
The AMIS-710322-A4 imaging array consists of 27 sensors, AMIS-720341 (PI3041) produced by AMIS, which are cascaded to provide
2592 photo-detectors with their associated multiplex switches and a digital shift register, which controls its sequential readout. Mounted
in the module is a one-to-one graded indexed micro lens array, which focuses the scanned documents to image onto its sensing plane.
The on-board amplifier processes the video signal to produce a sequential stream of video at the video output pin of the AMIS-710322-
A4 module.
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. I/O to the module is the 10-pin connector located on one end of the module. The cross section of the AMIS-
710322-A4 is shown in Figure 1 and the block diagram in Figure 2.
