AMIS-710325-A4: 300dpi CIS Module

Data Sheet

1.0 General Description

The AMIS-710325-A4 (PI325MC-A4) is a contact image sensor (CIS) module which uses MOS image sensor technology for high-speed

performance and high sensitivity. The AMIS-710325-A4 is suitable for scanning A4 size (216mm) documents with 11.8 dots per

millimeter (dpm) resolution. Applications include fax machines, game systems, a 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

• 11.8dpm resolution, 216mm scanning length

• Up to 500µsec/line scanning speed with optional 5.2MHz pixel rate

• Wide dynamic range

• Analog output

• Red (660nm) LED light source

• Compact size ≅ 13mm x 19mm x 232mm

• Low power

• Light weight

3.0 Functional Description

The AMIS-710325-A4 imaging array consists of 27 sensors, AMIS-720321 (PI3021), produced by AMI Semiconductor, are cascaded to

provide 2592 photo-detectors with their associated multiplex switches and a digital shift register, controls its sequential readout.

Mounted in the module is a one-to-one graded indexed micro lens array, 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 of the AMIS-

710325-A4 module.

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, acts 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-

710325-A4 is shown in Figure 1 and the block diagram in Figure 2.
