KAF-4320
2084 (H) x 2085 (V) Full
Frame CCD Image Sensor
Description
The KAF4320 Image Sensor is a high performance monochrome
area CCD (charge-coupled device) image sensor designed for a wide
www.onsemi.com
range of image sensing applications.
The sensor incorporates true two-phase CCD technology,
simplifying the support circuits required to drive the sensor as well as
reducing dark current without compromising charge capacity.
The sensor also utilizes the TRUESENSE Transparent Gate Electrode
to improve sensitivity compared to the use of a standard front side
illuminated polysilicon electrode.
The full imaging array is read out of four outputs, each of which is
driven by a low impedance two stage source follower that provides
a high conversion gain. This combination enables low noise at a net
readout rate of 12 MHz (3 MHz per output).
