AMIS-710250: 200dpi Module
AMIS-710250 (PI250MC-A6) contact imaging sensor (CIS) module. successor module predecessor, AMIS710223-A6 (PI223MC-A6) possesses superb qualities predecessor; except, outstanding feature operate from single supply. Like predecessor, composed AMIS-720220 (PI3020) sensor chips. AMIS-720220 dots inch (dpi) solid-state line imaging array, also product Semiconductor. This imaging device fabricated using imaging sensor technology high-speed performance high sensitivity. Like predecessor, AMIS-710250 suitable scanning size (104mm) documents with dots millimeter (dpm) resolution. Applications include ticket, check card scanners, variety mark readers other automation equipment.
Features
power-single power supply 5.0V Light source, lens sensor integrated into single module 8dpm resolution, 104mm scanning length High speed page scan 167µsec/line 5MHz pixel rate with internal optical modification (optional feature) Wide dynamic range Analog output Yellow-Green light source Compact size 14mm 19mm 120mm Light weight
Functional Description
AMIS-710250 consists imaging array sensors that cascaded provide photo-detectors. Each sensor associated multiplex switches digital shift register that controls sequential readout. Each sensor also contains chip-select switch that each following chip accessed sequentially predecessor chip completes scan. These chips mounted printed circuit board (PCB) along with clock buffers video signal amplifier. only change from predecessor module this amplifier. been slightly altered from predecessor module gain single supply feature, Figure

Figure AMIS-710250 Cross Sectional View
This pictorial cross section shows light source illumination path. light document reflects images document. reflected images focus through micro lens onto chips' image sensing line where images converted proportional electrical charges. board amplifier processes these signal charges into proportional video signal voltages, which sent output video port.
