Analog to Digital Converters - ADC
Analog Devices


The AD9943KCPZ  /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 AD9943KCPZ/AD9944 consists of a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA), and a black level clamp. The AD9943KCPZ offers 10-bit ADC resolution, while the AD9944 contains a true 12-bit ADC.
