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.

2.0 Key Features

• Light source, lens and sensor are integrated into a single module

• 8dpm resolution, 307mm scanning read length

• High speed page scan - up to 490µsec/line @ 5MHz pixel rate

• Wide dynamic range

• One analog output

• Super super Red (630nm) LED light source

• Compact size ≅ 20.5mm x 21.5mm x 324mm

• Low power

• Light weight

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.
