PRODUCT DESCRIPTION
The AD9806 is a complete analog signal processor for CCD
applications. It features an 18 MHz single-channel architecture
designed to sample and condition the outputs of interlaced and
progressive scan area CCD arrays. The AD9806’s signal chain
consists of an input clamp, correlated double sampler (CDS),
digitally programmable gain amplifier (PGA), 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 AD9806 operates from a single 3 V power supply, typically
dissipating 75 mW. Packaged in a space-saving 48-lead LQFP,
the AD9806 is specified over an operating temperature range of
–20
°C to +85 C.
