PRODUCT DESCRIPTION

The AD9824 is a complete analog signal processor for CCD applications. It features a 30 MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The AD9824’s signal chain consists of an input clamp, a correlated double sampler (CDS), PxGA, a digitally controlled VGA, a black level clamp, and a 14-bit A/D converter. Additional input modes are also provided for processing analog video signals.
