Data Sheet
1.0 General Description
AMI Semiconductor’s AMIS-720658 (PI6058) contact image sensor (CIS) is a selectable 600 or 300 dot per inch (dpi) resolution linear image sensor, which employs AMI Semiconductor’s proprietary CMOS image sensing technology. The sensor contains an on-chip output amplifier, power down circuitry and parallel transfer features that are uniquely combined with the present-day active-pixel-sensor technology. The image sensors are designed to be cascaded end-to-end on a printed circuit board (PCB) and packaged in an image sensing module. Applications for the sensor array include facsimiles, PC scanners, check readers, and office automation equipment. Figure 1 is a block diagram of the sensor. Each sensor consists of 344 active pixels, their associated multiplexing switches, buffers and an output amplifier circuit with a power down feature. The sensors pixel-pixel spacing is approximately 42.3m. The size of each sensor without the scribe lines is 14560m by 335m.
