Product Summary
The AD9844AJSTZ is a complete analog signal processor for CCD applications. The AD9844AJSTZ features a 20 MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The internal registers are programmed through a 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, input configuration, and power-down modes. The AD9844AJSTZ operates from a single 3 V power supply, typically dissipates 78 mW, and is packaged in a 48-lead LQFP. Applications are (1)digital still cameras; (2)digital video camcorders; (3)PC cameras.
