The AD9941 is a complete analog signal processor for imaging applications that do not require correlated double sampling (CDS). It is also suitable for processing the output signal from the AD9940 CDS front end product. It features a 56 MHz, single-channel architecture designed to sample and condition the output of CMOS imagers and CCD arrays already containing on-chip CDS. The AD9941 signal chain consists of a differential input sample-and-hold amplifier (SHA), a digitally controlled variable gain amplifier (VGA), a black level clamp, and a 14-bit ADC.
The internal registers are programmed through a 3-wire serial digital interface.
The AD9941 operates from a single 3 V supply, typically dissipates 145 mW, and is packaged in a 48-lead LQFP.
- Digital still cameras using CMOS imagers
- Professional HDTV camcorders
- Professional/high-end digital cameras
- Broadcast cameras
Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
