AMIS-710240: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710240 (PI240MC-A4) is a contact imaging sensor (CIS) module composed of 1728 AMIS-720033 (PI3020) sensor chips.
The AMIS-720033 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-710240 is suitable for
scanning A4 size (21mm) documents with 8 dots per millimeter (dpm) resolution. Applications include variety of document scanners,
variety of mark readers and other automation equipment.
2.0 Key Features
• Inverted video signals (magnitude increases in a negative direction)
• Light source, lens and sensor are integrated into a single module
• 8dpm resolution
• 216mm scanning length
• 0.347ms/line scanning speed, operated @ 5.0MHz
• Wide dynamic range analog output
• 660nm light source
• Compact size: ≈ 14mm 19.5mm x 232mm
• Low power
• Light weight
3.0 Functional Description
The AMIS-710240 imaging array consists of 27 chips that are cascaded to provide 1728 photo-detectors with their associated multiplex
switches and a digital shift register that controls its sequential readout. Mounted in the module is a 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-710240 module.
