Product Details
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.
APPLICATIONS
- Digital still cameras using CMOS imagers
- Professional HDTV camcorders
- Professional/high-end digital cameras
- Broadcast cameras
