AMIS-710625

AMIS-710625-A6: 600pdi CIS Module Data Sheet 1.0 General Description The AMIS-710625-A6 (PI625MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720639 (PI3039) sensor chips. The AMIS-720639 is a 600dpi solid-state line imaging array, also a product of AMI Semiconductor. This imaging device is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710625-A6 is suitable for scanning A6 size (104mm) documents with 23.62 dots per millimeter (dpm) resolution. Applications include ticket, check and card scanners, a variety of mark readers, and other automation equipment. 2.0 Key Features • • • • • • • • • Light source, lens and sensor are integrated into a single module 23.62 dots/mm resolution, 104mm scanning length Up to 500µs ec/line scanning speed, with 5MHz pixel rate Wide dynamic range Analog output Red 660nm LED light source Compact size ≅ 14mm x 19.5mm x 120mm Low power Light weight 3.0 Functional Description The AMIS-710625-A6 imaging array consists of 13 sensors that are cascaded to provide 2496 photo-detectors with their associated multiplex switches, and a digital shift register that controls its sequential readout. Mounted in the module is one-to-one graded indexed micro lens array that 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-710625-A6 module. Illumination is by means of an integrated LED light source. All components are housed in a small plastic housing which has a cover glass that 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-710625-A6 is shown in Figure 1 and its block diagram in Figure 2.
