ICX274AL
Diagonal 8.923mm (Type 1/1.8) Progressive Scan CCD Image Sensor with Square Pixel for B/W Video Cameras
Description
The ICX274AL is a diagonal 8.923mm (Type 1/1.8)
interline CCD solid-state image sensor with a square
pixel array and 2.01M effective pixels. Progressive
scan allows all pixels' signals to be output
independently within approximately 1/15 second,
and output is also possible using various addition
and pulse elimination methods. This chip features an
electronic shutter with variable charge-storage time
which makes it possible to realize full-frame still
images without a mechanical shutter. Further, high
sensitivity and low dark current are achieved through
the adoption of Super HAD CCD technology.
This chip is suitable for image input applications
such as still cameras which require high resolution,
etc.
20 pin DIP (Plastic)
