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

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.
7.0 Switching Characteristics (25°C)
The switching characteristics for the I/O clocks are shown in Figure 4. The timing parametric values and their symbols are given in
Table 4.
