General Description
AMI Semiconductor’s AMIS-720649 (PI6049A) contact image sensor (CIS) is a 600 dots 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 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.
