AMIS-710411-A7 Datasheet | AMI SEMICONDUCTOR

Description The AMIS-710411-A7 (PI411MC-A7) is a contact imaging sensor (CIS) module that can operate from a single 5.0V supply. It is a linear scanning array posed of 11 AMIS-720422 (PI3022) imaging sensor chips. The AMIS-720422 is a 400 dots per inch (dpi) solid-state line imaging sensor chip with 128 photo sensitive elements, which are also a product of AMIS. Eleven of these devices are sequentially cascaded to form the linear scanning array with a total of 1408 photo sensing elements. This imaging device is fabricated using MOS imaging sensor technology for its high-speed performance and high sensitivity. It is designed for scanning A7 size (89mm) documents with 400dpi resolution. Applications include ticket, check and card scanners, a variety of mark readers, and other automation equipment. 2.0 Key Features - - - - - - - - - Low power-single power supply at 5.0V Light source, lens and sensor are integrated into a single module 15.7dpm resolution, 89mm scanning length High speed page scan - up to 282µsec/line @ 5MHz pixel rate Wide dynamic range Analog output 660 LED light source pact size ≅ 13mm x 25.6mm x 102mm Light weight 3.0 Functional Description The AMIS-710411-A7 consists of 11 imaging array sensors, which are cascaded to provide 1408 photo-detectors. Each sensor has its associated multiplex switches and a digital shift register, which controls its sequential readout. Each sensor also contains a chip select switch so that each following chip is accessed sequentially as its predecessor chip pletes its scan. Theses chips are mounted on a printed circuit board (PCB) along with clock buffers and a video signal amplifier (see Figure 1). .. The PCB containing the imaging array is enclosed in a module housing along with a one-to-one graded indexed micro lens array, which focuses the image of the scanned documents onto the sensing line of the sensor chips. The document is illuminated with an LED light source, which is also mounted in the housing (see Figure...
