1.0 General Description
The AMIS-710403-A6 (PI403MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720422 (PI3022)
sensor chips. The AMIS-720422 is a 400 dots per inch (d pi) solid-state li ne imaging arr ay, also a product of AMIS. This imaging devic e
is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710403-A 6 is suitable
for scanning A6 size (104mm) documents with 16 dots per millimeter (dpm) resolution. Applications include ticket, check and card
scanners, a variety of mark readers and other automation equipment.
2.0 Key Features
• Light source, lens and sensor are integrated into a single mo dule
• 16dpm resolution, 104mm scanning length
• Up to 333µsec/line scanning speed, with 5M Hz pixel rate
• Wide dynamic range
• Analog output
• Red LED light source (660nm)
• Compact size ≅ 14mm x 19mm x 120mm
• Low powe r
• Light weight
3.0 Functional Description
The AMIS-710403-A6 imaging arra y consists of 13 sensors, which are cascaded to provide 1664 ph oto-detectors with their associated
multiplex switches and a digital shift register, which controls its sequential readout. Mounted in the module is one-to-one graded
indexed micro lens arr a y, which focus es the s cann ed doc uments to im age onto its s ensi n g plan e. The on-board ampl ifier proc esses the
video signal to produce a se quential stream of video at the video output pin of the AMIS-710403-A6 module.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a smal l plastic housing with a
cover glass, which 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 (see Figure 4). T he cross s ection of
the AMIS-710403-A6 is shown in Figure 1 and the block diagram in Figure 2.
