AMIS-710225: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710225 (PI225MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720220 (PI3020) sensor
chips. The AMIS-720220 is a 200 dots per inch (dpi) 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-710225 is
suitable for scanning A6 size (104mm) documents with 8 dots per millimeter (dpm) resolution. Applications include ticket, check and
card scanners, variety of mark readers, and other automation equipment.
2.0 Key Features
• Light source, lens and sensor are integrated into a single module
• 8dpm resolution, 104mm scanning length
• High speed page scan - up to 167µsec/line @ 5MHz pixel rate
• Wide dynamic range
• Analog output
• Red LED light source
• Compact size ≅ 14mm x 19mm x 120mm
• Low power
• Light weight
3.0 Functional Description
The AMIS-710225 imaging array consists of 13 sensors that are cascaded to provide 832 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-710225 module.
wwIlwlu.mDaintaaStihoeneti4sUa.ccocmomplished 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
AMIS-710225 is shown in Figure 1 and the block diagram in Figure 2.
