AMIS-710310-DR: 300dpi Two-Level Digital Output Module Data Sheet
1.0 General 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 compression is required, such as in data transmissions.
• Where component 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)
• Compact size ≅ 13mm x 25.6mm x 102mm low power
• Light weight

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 and passes them to the analog digitizing circuit, where video pixels are converted to digital signal and passed to the
output of the module. See Figure 1.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing with a
cover glass which acts as the focal point for the object being scanned and protects the imaging array, the micro lens assembly, and the
LED light source from dust. The pictorial of the AMIS-710310-DR cross section is shown in Figure 2.

I/O to the module is an 8-pin flex cable connector (see I/O Connector, under Specifications) located on one end of the module. The
connector is on the top of the module with the glass window facing down and it is located on the opposite side of the module (see the
Mechanical Housing under Mechanical Structure).
