CDS-1402 - ETC

CDS-1402 14-Bit / Very Fast Settling Correlated Double Sampling Circuit

The CDS-1402 is an application-specific, correlated double sampling (CDS) circuit designed for electronic-imaging applications that employ CCD's (charge coupled devices) as their photodetector. The CDS-1402 has been optimized for use in digital video applications that employ 10 to 14-bit A/D converters. The low-noise CDS-1402 can accurately determine each pi.
