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 pro-vided for processing analog video signals.
The internal registers are programmed through a 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, input configuration, and power-down modes.The AD9824 operates from a single 3 V power supply, typically dissipates 153 mW, and is packaged in a 48-lead LFCSP.
