AMIS-710403

AMIS-710403-A6: 400dpi CIS Module Data Sheet 1.0 General Description The AMIS-710403-A6 (PI403MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720422 (PI3022) sensor chips. The AMIS-720422 is a 400 dots per inch (dpi) solid-state line imaging array, also a product of AMIS. This imaging device is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710403-A6 is suitable for scanning A6 size (104mm) documents with 16 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 16dpm resolution, 104mm scanning length Up to 333µsec/line scanning speed, with 5MHz pixel rate Wide dynamic range Analog output Red LED light source (660nm) Compact size ≅ 14mm x 19mm x 120mm Low power Light weight 3.0 Functional Description The AMIS-710403-A6 imaging array consists of 13 sensors, which are cascaded to provide 1664 photo-detectors with their associated multiplex switches and a digital shift register, which controls its sequential readout. Mounted in the module is 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-710403-A6 module. Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing with 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-710403-A6 is shown in Figure 1 and the block diagram in Figure 2.
