AMIS-710208-A7: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710208-A7 (PI208MC-A7) is a contact image sensor (CIS) module containing contact image sensors, using MOS image
sensor technology for high-speed performance and high sensitivity. The AMIS-710208-A7 is designed to scan documents with a short
read length of 88mm. The module produces a single stream of sampled analog video proportional to images of a single horizontal line
scan that is stepped vertically down a document page with a resolution of 8 dots per millimeter (dpm) and a width of 88mm.
Applications include fax machines, game systems, variety of mark readers, and other automation equipment requiring document
scanners.
2.0 Key Features
Light source, lens and sensor are integrated into a single module
8dpm resolution, 88mm scanning length
Up to 176µsec/line scanning speed, with 4MHz pixel rate (see Table 3, Note 2)
Wide dynamic range
660nm light source
Compact size 13mm x 25.6mm x 102mm
Low-power
Light weight
3.0 Functional Description
The AMIS-710208-A7 imaging array consists of 11 AMIS-720233 (PI3033B) sensors, produced by AMIS, which are cascaded together
to provide 704 photo-detectors (pixels) with their associated multiplex switches, and a digital shift register that controls its sequential
readout. Each sensor is sequentially connected to initiate its scanning process at completion of its predecessor’s scan.
wwMwo.DunattaeSdhienett4hUe.cmomodule is a one-to-one graded-indexed micro lens array that focuses the image to be scanned onto the linear array
pixels. The incident image is converted to an electrical signal and then the charge on each pixel is transferred to a common video line.
The charge on each pixel is then converted to a voltage by a single video amplifier. The module output is then available on Pin 1 of the
connector, Vout.
Illumination is by means of an integrated LED light source. All components are housed in a small plastic housing which has a cover
glass that acts as the focal point for the object being scanned. In addition, it protects the imaging array, micro lens assembly and LED
light source from dust.
Inputs and outputs (I/O’s) to and from the module are by an 8-pin connector, located on one end of the module. A cross-section of the
AMIS-710208-A7 module is shown in Figure 1 and a block diagram in Figure 2.
