AMIS-710250: 200dpi CIS Module Data Sheet 1.0 General Description The AMIS-710250 (PI250MC-A6) is a contact imaging sensor (CIS) module. It is a successor module to its predecessor, AMIS710223-A6 (PI223MC-A6) it possesses all superb qualities of its predecessor; except, it has one outstanding feature - it can operate from a single 5V supply. Like its predecessor, it is posed of 13 AMIS-720220 (PI3020) sensor chips. The AMIS-720220 is a 200 dots per inch (dpi) solid-state line imaging array, also a product of AMI Semiconductor. This imaging device is fabricated using MOS imaging sensor technology for its high-speed performance and high sensitivity. Like its predecessor, the AMIS-710250 is suitable for scanning A6 size (104mm) documents with 8 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 - - - - - - - - - Low power-single power supply at 5.0V Light source, lens and sensor are integrated into a single module 8dpm resolution, 104mm scanning length High speed page scan - up to 167µsec/line @ 5MHz pixel rate with internal optical modification (optional feature) Wide dynamic range Analog output Yellow-Green LED light source pact size ≅ 14mm x 19mm x 120mm Light weight 3.0 Functional Description The AMIS-710250 consists of 13 imaging array sensors that are cascaded to provide 832 photo-detectors. Each sensor has its associated multiplex switches and a digital shift register that 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. These chips are mounted on a printed circuit board (PCB) along with clock buffers and video signal amplifier. The only change from its predecessor module is in this .. amplifier. It as been slightly altered from its predecessor module to gain the single supply feature, see...
