PI331MC-DR Datasheet | AMI SEMICONDUCTOR

Features - Light source, lens, and sensor are integrated into a single module - 11.8 dpm resolution, 89 mm scanning length - Up to 600 µsec/line scanning speed, with 2 MHz pixel rate (See Table 3, Note 3.) (Other speeds are also available) - Wide dynamic range - Two-Level Tracking Digital Output (“Dynamic Threshold Digitizer”) - Red light source 660nm (Other colors are available) - pact size ≅ 13 mm x 25.6 mm x 102 mm - Low power - Light weight General Description The PI331MC-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 “backgroundtracking”, two-level digital output signals. It is based on CIS module, the PI305M-A6 manufactured by PIC, but with a shorter read length of 89 mm. Hence, its performance is equivalent to the PI305M-A6 that uses MOS image sensor technology to gains its highspeed performance and high sensitivity. The PI331MC-DR is suitable for scanning documents with width of 89 mm and with resolution of 11.8 dots per millimeter. Its has a .. broad applications, but specially designed for the following areas: - Where data pression is required, such as in data transmissions. PAGE 1 OF 9 - PI331MC-DR, 11-8-00 - Where ponent pin-out count must be kept to a minimum. The background-tracking-digitizing circuits in the PI331MC-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”.
