AMIS-722402: Contact Image Sensor
Data Sheet
1.0 General Description
AMI Semiconductor’s AMIS-722402 (PI5002D) contact image sensor (CIS) consists of 1376 active pixels which enables the selection of
2400, 1200, 600, or 300 dots per inch (dpi) resolutions, and 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 includes facsimiles, PC
scanners, check readers, and office automation equipment.
Figure 1 is a block diagram of the sensor, showing 1376 active pixels, their associated multiplexing switches, buffers, and an output
amplifier circuit with a power down feature. The sensors pixel-pixel spacing is approximately 10.58
