AD9945KCPZ

ANALOG DEVICES  AD9945KCPZ  芯片, CCD信号处理器, 12位, 32-LFCSP

The is a complete Analog Signal Processor for CCD applications. It features a 40MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The AD9945"s signal chain consists of a correlated double sampler CDS, a digitally controlled variable gain amplifier VGA, a black level clamp and a 12-bit A/D converter. The internal registers are programmed through a 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, input clock polarity and power-down modes.
