CCD181
GENERAL DESCRIPTION
The CCD181 is a 2592-element line image sensor designed for industrial measurement, telecine, and document scanning applications which require high resolution, high sensitivity and high data rate.
Incorporation of on-chip anti-blooming and integration controls allow the CCD181 to be extremely useful in an industrial measurement and control environment or in environments where lighting conditions are difficult to control.
The CCD181 is equipped with special gates which allow the user to select 4 effective array lengths:
2592 elements: 300-lines/inch across 8.
5 inch wide document 2048 elements: 240-lines/inch across 8.
5 inch wide document 1728 elements: 200-lines/inch across 8.
5 inch wide document 1024 elements: 120-lines/inch across 8.
5 inch wide document
The CCD181 is a third generation device having an overall improved performance compared with first and second generation devices, including enhanced blue response and excellent low light level performance, and high-speed operation up to 20 MHz.
The photoelement size is 10µm (0.
39 mils) x 10µm (0.
39 mils) on 10µm (0.
39 mils) centers.
The device is manufactured using Fairchild Imaging’s advanced charge-coupled device n-channel isoplanar buried-channel technology.
