Overview
AMIS-710214: 200dpi Two Level Digital Output Module Data Sheet 1.
0 General Description The AMIS-710214 (PI214MC-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 AMI Semiconductor’s CIS module that employs MOS image sensor technology to gain its high-speed performance and high sensitivity.
The AMIS-710214 is suitable for scanning documents with width of 216mm and with resolution of 8 dots per millimeter (dpm).
It has broad applications, but is specially 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-710214 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”.
