KAF-16803 4096 (H) x 4096 (V) Full Frame CCD Image Sensor Description The KAF16803 image sensor is a redesigned version of the popular KAF16801 image sensor (4096(H) 4096(V) pixel www.onsemi.com resolution), with enhancements that specifically target the needs of high performance digital radiography applications. Improvements include enhanced quantum efficiency for improved DQE at higher spatial frequencies, lower noise for improved contrast in areas of high density, and anti-blooming protection to prevent image bleed from over exposure in regions outside the patient. The sensor utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode, as well as microlenses to maximize light sensitivity. When combined with large imaging area and small pixel size, the KAF16803 provides the sensitivity, resolution and contrast necessary for high quality digital radiographs. To simplify device integration, the KAF16803 image sensor uses the same pin-out and package as the KAF16801 image sensor. Figure 1. KAF16803 CCD Image Sensor Table 1.
