AD9945KCPZ

AD9945 is a complete analogue signal processor for CCD applications. It features a 40MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The AD9945’s signal chain consists of a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA), a black level clamp and a 12bit A/D converter. Typical applications include digital still cameras, digital video camcorders, PC cameras, portable CCD imaging devices and CCTV cameras.
