PRODUCT DESCRIPTION
The AD9846A is a complete analog signal processor for CCD
applications. It features a 30 MHz single-channel architecture
designed to sample and condition the outputs of interlaced and
progressive scan area CCD arrays. The AD9846A’s signal chain
consists of an input clamp, correlated double sampler (CDS),
Pixel Gain Amplier (PxGA), digitally controlled variable gain
amplier (VGA), black level clamp, and a 10-bit A/D con-
verter. 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
adjustment, black level adjustment, input conguration, and
power-down modes.
The AD9846A operates from a single 3 V power supply, typi-
cally dissipates 117 mW, and is packaged in a 48-lead LQFP.
