AMIS-710216: 200dpi Two Level Digital Output Module
Data Sheet
1.0 General Description
The AMIS-710216 (PI216MC-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. It is based on CIS module, the AMIS-
710209-A6 (PI209M-A6) manufactured by AMIS, but with a shorter read length of 88mm. Hence, its performance is equivalent to the
AMIS-710209-A6 which uses MOS image sensor technology to gain its high-speed performance and high sensitivity. The AMIS-710216
is suitable for scanning documents with width of 88mm and with resolution of 8 dots per millimeter (dpm). It has broad applications, but
it was especially 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-710216 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
• 8dpm resolution, 88mm scanning length
• Up to 176µsec/line scanning speed, with 4MHz pixel rate (See Table 3, Note 3)
• Wide dynamic range
• Two-level tracking digital output (“Dynamic Threshold Digitizer”)
• 660nm light source (other colors available)
• Compact size ≅ 13mm x 25.6mm x 102mm
• Low power
• Light weight

Notes:
1. VLED sources are also available from 5 to 24V.
2. Clock pulse high is specified at 4.0MHz at 25 percent duty.
3. The tint is specified with the maximum 4.0MHz clock frequency. In operation, the time constants in the reference generator is set to match the initial exposure
time, hence the optimum integration time will be set by 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 the
Table 4.
