AMIS-710310-DR Datasheet | AMI SEMICONDUCTOR

Description The AMIS-710310-DR (PI310MC-DR) is a contact image sensor (CIS) module with an additional on-board circuit that digitizes the analog pixels from the CIS image sensor to a “background-tracking”, two-level digital output signal. The module uses MOS image sensor technology to gain high-speed performance and high sensitivity. The AMIS-710310-DR is suitable for scanning documents with widths of 89mm and with resolutions of 11.8 dots per millimeter (dpm). It has broad applications but is specifically designed for the following areas: - Where data pression is required, such as in data transmissions. - Where ponent pin-out count must be kept to a minimum. The background-tracking-digitizing circuits in the AMIS-710310-DR have been referred to as the “dynamic threshold” two-level A/D converter. For the purpose of describing the module’s characteristics, this “dynamic threshold” processing circuit shall herein be referred to as the “tracking digitizer”. 2.0 Key Features - - - - - - - Light source, lens and sensor are integrated into a single module 11.8dpm resolution, 89mm scanning length Up to 423µsec/line scanning speed, with 2.5MHz pixel rate (see Table 3, Note 3) Wide dynamic range two-level tracking digital output (“Dynamic Threshold Digitizer”) Standard Yellow-Green light source (other colors are available) pact size ≅ 13mm x 25.6mm x 102mm low power Light weight 3.0 Module Description ..

AMIS-710310-DR: 300dpi Two-Level Digital Output Module Data Sheet The AMIS-710310-DR module consists of 11 sensors that are cascaded to provide 1056 photo-detectors with their associated multiplex switches and a digital shift register that controls its sequential readout. Mounted in the module is a one-to-one graded-indexed micro lens array that focuses the scanned documents to image onto its sensing plane. A buffer amplifier amplifies the video pixels from the image sensors...
