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.
