AMIS-710250: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710250 (PI250MC-A6) is a contact imaging sensor (CIS) module. It is a successor module to its predecessor, AMIS-
710223-A6 (PI223MC-A6) it possesses all superb qualities of its predecessor; except, it has one outstanding feature - it can operate
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-710250 is suitable for
scanning A6 size (104mm) documents with 8 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
• 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 with internal optical modification (optional feature)
• 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-710250 consists of 13 imaging array sensors that are cascaded to provide 832 photo-detectors. Each sensor has 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 as been slightly altered from its predecessor module to gain the single supply feature, see Figure 1.
