The AD9821 is a 12-bit, 40 MSPS analog front-end designed for high-performance CMOS imagers. It contains all the circuitry necessary to acquire, condition, and digitize a signal from a CMOS sensor, a CCD that contains a correlated double sampler, or a standalone correlated double sampler like the AD9823.
