AAMMISI-7S10330: 300dpi CIS Two-Level Digital Output Module
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

Notes:
(1) VLED sources are also available in 5V.
(2) Clock pulse high is specified at 2.5MHz at 25 percent duty.
(3) The tint is specified with a 2.5MHz clock frequency. In operation, the time constants in the reference generator are set to match the initial exposure time, hence
the time constant will determine the optimum integration time. Accordingly, it is highly recommended that the parameters be factory adjusted for the specific
applications.
