PRODUCT DESCRIPTION
The AD9843A is a complete analog signal processor for CCD
applications. It features a 20 MHz single-channel architecture
designed to sample and condition the outputs of interlaced and
progressive scan area CCD arrays. The AD9843A’s signal chain
consists of an input clamp, correlated double sampler (CDS),
digitally controlled variable gain amplifier (VGA), black level
clamp, and 10-bit A/D converter. Additional input modes are
provided for processing analog video signals.
The internal registers are programmed through a 3-wire serial
digital interface. Programmable features include gain adjust-
ment, black level adjustment, input configuration, and power-
down modes.
The AD9843A operates from a single 3 V power supply, typi-
cally dissipates 78 mW, and is packaged in a 48-lead LQFP.
