The AD9845B is a 12-bit 30 MSPS CCD signal processor with low noise clamp circuits, pre-blanking function, auxiliary inputs VGA and input clamp, 3-wire serial digital interface, 3 V single-supply operation and low power.
The AD9845B is an improved version of the AD9845A CCD signal processor designed for high-performance digital still cameras and industrial/scientific imaging. It features a 30 MHz single-channel architecture to sample and condition outputs from interlaced and progressive scan area CCD arrays. The signal chain includes an input clamp, correlated double sampler (CDS), pixel gain amplifier (PxGA), a digitally controlled variable gain amplifier (VGA), a black level clamp, and a 12-bit A/D converter.
