AMIS-710252-A6:
200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710252-A6 (PI252MC-A6-R) is a contact imaging sensor (CIS) module. It operates from a single 5V supply. It is composed
of 13 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. The AMIS-710252-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.

3.0 Functional Description
The AMIS-710252-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. Theses 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).
