AD9822: Complete 14-Bit CCD/CIS Signal Processor
The AD9822 is a complete analog signal processor for CCD imaging applications. It features a 3-channel architecture designed to sample and condition the outputs of trilinear color CCD arrays. Each channel consists of an input clamp, Correlated Double Sampler (CDS), offset DAC and Pro-grammable Gain Amplifier (PGA), multiplexed to a high performance 14-bit A/D converter.
