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. Key Features • 600dpi • 344 image sensor elements (pixels) • 42.3µm pixel center-to-center spacing (23.62dots/mm) • On-chip amplifier • Single 5.0V power supply • 5.0V input clocks • 2.5MHz maximum pixel rate • Parallel / integrate and transfer • Power-down circuit • High sensitivity • Low power • Low noise
