14-Bit, 5 Megapixels/Second Imaging Signal Processor

The ADCDS-1405 is an application-specific Video signal processor designed for electronic-imaging applications that employ CCD's (charge coupled devices) as their photodetector. The ADCDS-1405 incorporates a "user configurable" input Amplifier a CDS (correlated double sampler) and a sampling A/D converter in a single package, providing the user with a complete, high performance, low- cost, low-power, integrated solution. The key to the ADCDS-1405 's performance is a unique, high- speed, high-accuracy CDS circuit, which eliminates the effects of residual charge, charge injection and "kT/C" noise on the CCD's output floating capacitor, producing a "valid video" output signal. The ADCDS-1405 digitizes this resultant "valid video" signal using a high-speed, low-noise sampling A/D converter By C&D Technologies.
