The AD9804JST is a complete analog signal processor designed for CCD applications, featuring a 10-bit, 18 MSPS A/D converter. The device integrates an input clamp, correlated double sampler (CDS), digitally controlled variable gain amplifier (VGA) with 6 dB to 40 dB range, and a black level clamp. It operates on a single 3 V supply and utilizes a 3-wire serial digital interface for register programming. The component is housed in a 48-lead LQFP package.
The AD9804JST is the tape-and-reel variant of the AD9804 CCD signal processor. It belongs to a family of complete analog signal processors that include similar models such as the AD9806, AD9840A, and AD9843A, which offer varying sampling rates up to 40 MSPS.
