Data Sheet
1.0 General Description
The AMIS-710330 (PI330MC-DR) is a contact image sensor (CIS) module with an additional on board circuit, which 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-710330 is suitable for scanning documents with widths of
89mm and 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-710330 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”)
Infared light source 880nm (other colors are available)
Compact size 13mm x 25.6mm x 102mm
Low power
Light weight

Data Sheet
The AMIS-710330 module consists of 11 sensors, which are cascaded to provide 1056 photo-detectors with their associated multiplex
switches and a digital shift register, which controls its sequential readout. Mounted in the module is a one-to-one graded-indexed micro
lens array, which 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 an analog digitizing circuit, where the video pixels are converted to a 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 AMIS-710330 cross section is shown in Figure 2.

I/O to the module is an 8-pin flex cable connector (see I/O Connector, in Section 5.0) 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 in Section 9.0).
