AMIS-710330: 300dpi CIS Two-Level Digital Output Module
AMIS
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”.
