AMIS-710239-A3: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710239-A3 (PI239MC-A3-R) is a contact image sensor (CIS) module. It is a long contact image sensor, which uses MOS
image sensor technology for high speed performance. The AMIS-710239-A3 is suitable for scanning A3 size (307mm) documents with
eight dots per millimeter (dpm) resolution. Hence, there are 38 AMIS-720233 (PI3033B) image sensors in the module, providing a total
of 2432 pixels in a sequence. The sensors are 200 dots per inch (dpi) solid-state line imaging array, also a product of AMI
Semiconductor. Applications include document scanners, mark readers and other office automation equipment.

3.0 Functional Description
The AMIS-710239-A3 imaging array consists of 38 sensor chips in the module, which are sequentially cascaded to provide 2432 photo-
detectors with their associated multiplex switches and a digital shift register, which controls its sequential readout. Mounted in the
module is a one-to-one graded indexed micro lens array, which 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.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing which
has a cover glass acting as the focal point for the object being scanned and protects the imaging array, micro lens assembly and LED
light source from dust. I/O to the module is the 10-pin connector, located on one end of the module. The cross section of the AMIS-
710239-A3 is shown in Figure 1 and the block diagram in Figure 2.
