The AD9821 is a complete analog signal processor for imaging applications that do not require Correlated Double Sampling (CDS). It features a 40 MHz single-channel architecture designed to sample and condition the outputs of CMOS imagers and CCD arrays already containing on-chip CDS. The AD9821's signal chain consists of a differential input sample-and-hold amplifier (SHA), digitally controlled variable gain amplifier (VGA), black level clamp, and a 12-bit ADC. The internal registers are programmed through a 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, and power-down modes.
