GENERAL DESCRIPTION

The AD9943/AD9944 are complete analog signal processors for CCD applications. They feature a 25 MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The signal chain for the AD9943/AD9944 consists of a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA), and a black level clamp. The AD9943 offers 10-bit ADC resolution, while the AD9944 contains a true 12-bit ADC.
