AMIS-710254-A6: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710254-A6 (PI254MC-A6-R) is a contact imaging sensor (CIS) module. It operates from a single 5V supply. The module
contains of 13 image sensor chips (AMIS-720233 (PI3033) sensor chips). The AMIS-720233 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-710254-A6 is suitable for scanning A6 size (104mm)
documents with eight 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
• 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-710254-A6 consists of 13 imaging array sensors, which are cascaded to provide 832 photo-detectors. Each sensor contains
its associated multiplex switches and a digital shift register, which 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 a video signal amplifier. The only change from its predecessor module is in
this amplifier. It was slightly altered to gain the single supply feature through the application of the new rail-to-rail single volt operational
amplifiers (see Figure 1).
