AMIS-710240: 200dpi CIS Module Data Sheet
1.0 General Description
The AMIS-710240 (PI240MC-A4) is a contact imaging sensor (CIS) module composed of 1728 AMIS-720033 (PI3020) sensor chips.
The AMIS-720033 is a 200 dots per i nch (dpi) sol id-state line im aging array, also a prod uct of AMI Semiconductor. T his imaging devic e
is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710240 is suitable for
scanning A4 size (21mm) documents with 8 dots per millimeter (dpm) resolution. Applications include variety of document scanners,
variety of mark readers and other automation equipment.
2.0 Key Features
• Inverted video signals (magnitude increases in a negative direction)
• Light source, lens and sensor are integrated into a single mo dule
• 8dpm resolution
• 216mm scanning length
• 0.347ms/line scanning spee d, operated @ 5.0MHz
• Wide dynamic range analog output
• 660nm light source
• Compact size: ≈ 14mm 19.5mm x 232mm
• Low power
• Light weight
3.0 Functional Description
The AMIS-710240 imaging ar ray consists of 27 chips that are cascad ed to provide 1728 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. The on-board amplifier processes the video signal to
produce a sequential stream of video at the video output pin of the AMIS-710240 module.

Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing which
has a cover glass that acts as the focal point for the object being scanned and protects the imaging array, micro lens assembly and
LED light source from dust. I/O to the module is the 10-pin connector located on one end of the module. See Figure 4. The cross
section of the AMIS-710240 is sho wn in Figure 1 and the block diagram in Figure 2.

Note:
1. Tint is determined by the time interval between two SP. The longest integration time is determined by the degree of leakage current degradation that can be
tolerated by the system. A 10ms maximum is a typical rule-of-thumb, thus the experienced CIS user can use his discretion in determining the integration time.

Definition:
1. Tint: line scanning rate or integration time. Tint is determined by the interval of two SPs.
2. Freq is the main clock frequency.
3. Vpavg = ∑ Vp(n)/1728
4. Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
5. Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity percentage of adjacent pixels
6. Ud = Vdmax – Vdmin
Vd is the voltage amplitude between the output video's reset level and its dark level.
Vdmin is the minimum output with LED light off.
Vdmax: maximum output voltage with the LED light off
7. MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 4.0lp/mm
Vmin: minimum output voltage at 4.0lp/mm
8. lp / mm: line pair per mm
