AMIS-710322-A4
Overview
The AMIS-710322-A4 (PI322MC-A4) is a contact image sensor (CIS) module, which uses MOS image sensor technology for highspeed performance and high sensitivity. The AMIS-710322-A4 is suitable for scanning A4 size (216mm) documents with 11.8 dots per millimeter (dpm) resolution.
- 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
- 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-710322A4 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 AMIS710322-A4 is shown in Figure 1 and the block diagram in Figure
