- Wide dynamic range
- Two-Level Tracking Digital Output (“Dynamic Threshold Digitizer”)
- Infrared light source 880nm (Other colors are available)
- pact size ≅ 15 mm x 25.6 mm x 102 mm
- Low power
- Light weight General Description
The PI330MC-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 PI330MC-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.
- Where ponent pin-out count must be kept to a minimum.

The background-tracking-digitizing circuits in the PI330MC-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”.
