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 CDS functionality.
The Analog Devices AD9821 is a complete analog signal processor designed for imaging applications that do not require Correlated Double Sampling (CDS). It features a single-channel architecture with a differential input sample-and-hold amplifier, a digitally controlled variable gain amplifier, a black level clamp, and a 12-bit ADC. The device operates from a single 3 V power supply.
