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 10.58µm. The size of each sensor without

the scribe lines is 14560µm by 230µm.
