PRODUCT DESCRIPTIONThe AD9804 is a complete analog signal processor for CCD
applications. It features an 18 MHz single-channel architecture
designed to sample and condition the outputs of interlaced and
progressive scan area CCD arrays. The AD9804’s signal chain
consists of an input clamp, correlated double sampler (CDS),
digitally controlled VGA, black level clamp, and a 10-bit A/D
converter. The internal VGA gain register is programmed through
a 3-wire serial digital interface.

TIMING SPECIFICATIONSDATA OUTPUTS
NOTESMinimum CLPOB pulsewidth is for functional operation only. Wider typical pulses are recommended to achieve low noise clamp performance.
Specifications subject to change without notice
(CL = 20 pF, fCLK = 18 MHz, timing shown in Figures 1 and 2.)
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD9804 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
