AMIS-710400-A4

AMIS-710400-A4: 400dpi CIS Module Data Sheet 1.0 General Description The AMIS-710400-A4 (PI400M-A4) is a contact image sensor (CIS) module. It is a long contact image sensor, using MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710400-A4 is suitable for scanning A4 size (216mm) 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, 216mm scanning length 700µsec/line scanning speed @ 5.0MHz clock rate Wide dynamic range Analog output Yellow-Green light source 575nm Compact size ≅14.6mm x 19.5mm x 232mm Low power Light weight 3.0 Functional Description The AMIS-710400-A4 imaging array consists of 27 sensors, which are cascaded to provide 3456 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-710400-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 poin...
