www.analog.com GENERAL DESCRIPTION
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 signal
chain for the AD9943/AD9944 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 space-saving 32-lead LFCSP packages.
