The AD9841A and AD9842A are complete analog signal processors for CCD applications. Both products feature a 20 MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The AD9841A/AD9842A's signal chain consists of an input clamp, correlated double sampler (CDS), Pixel Gain Amplifier (PxGA), digitally controlled variable gain amplifier (VGA), black level clamp, and A/D converter. The AD9841A offers 10-bit ADC resolution, while the AD9842A contains a true 12-bit ADC. Additional input modes are provided for processing analog video signals.
