ADDI7100 CCD Signal Processor

The ADDI7100 is a complete analog signal processor for chargecoupled device (CCD) applications. It features a 45 MHz, single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The signal chain for the ADDI7100 consists of a correlated double sampler (CDS), a digitally controlled variable gain.
