AMIS-710404-A8: 400dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710404-A8 (PI404MC-A8) is a contact image sensor (CIS) module. It is a long contact image chip, which uses MOS image
sensor technology for high-speed performance and high sensitivity. The AMIS-710404-A8 is suitable for scanning A8 size (57mm)
documents with 15.7 dots per millimeter (dpm) resolution. Applications include document scanning, mark readers, gaming and office
automation equipment.
2.0 Key Features
• Light source, lens and sensor are integrated into a single module
• 15.7dpm resolution, 57mm scanning length
• 1.8msec/line scanning speed @ 500kHz clock rate
• Wide dynamic range
• Analog output
• Yellow-Green light source 570nm
• Compact size ≅ 13mm x 19mm x 70mm
• Low power
• Light weight
3.0 Functional Description
The AMIS-710404-A8 imaging array consists of 7 sensors, which are cascaded to provide 896 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-710404-A8 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 (see Figure 4). The cross
section of the AMIS-710404-A8 is shown in Figure 1 and the block diagram in Figure 2.
