AD9824 Complete 14-Bit 30 MSPS CCD Signal Processor

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.
