AD9943KCPZ
数据手册.pdf完整的10位和12位, 25 MHz的CCD信号处理器 Complete 10-Bit and 12-Bit, 25 MHz CCD Signal Processors
Product Details
The AD9943/AD9944 are complete analog signal processors for CCD applications. They feature a 25 MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The AD9943/AD9944’s signal chain consists of a correlated double sampler CDS, a digitally controlled variable gain amplifier VGA, and a black level clamp. The AD9943 offers 10-bit ADC resolution, while the AD9944 contains a true 12-bit ADC.
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.
The AD9943/AD9944 operate from a single 3 V power supply, typically dissipate 79 mW, and are packaged in a space-saving 32-lead LFCSP.
