AMIS-710251-A6: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710251-A6 (PI251MC-A6) is a contact imaging sensor (CIS) module. It is a successor module to its predecessor, AMIS-
710222-A6 (PI222MC-A6). This possesses all qualities of its predecessor, except, it has one outstanding feature - it operates from a
single 5V supply. Like its predecessor, it 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 its high-speed performance and high sensitivity. Like its predecessor, the AMIS-710251-A6 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
• Low power-single power supply at 5.0V
• 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
• Yellow-Green LED light source
• Compact size ≅ 14mm x 19mm x 120mm
• Light weight
3.0 Functional Description
The AMIS-710251-A6 consists of 13 imaging array sensors that are cascaded to provide 832 photo-detectors. Each sensor contains its
associated multiplex switches, and a digital shift register that controls its sequential readout. Each sensor also contains a chip-select
switch so that each following chip is accessed sequentially as its predecessor chip completes its scan. These chips are mounted on a
printed circuit board (PCB) along with clock buffers and video signal amplifier. The only change from its predecessor module is in this
amplifier. It has been slightly altered to gain the single supply feature through the application of the new rail-to-rail single volt
