The VSP2254 is a high-speed and high-resolution mixedsignal processing IC for CCD signal processing, which integrates two channels of correlated double sampling (CDS) and a 14-bit analog-to-digital converter. The VSP2254 also provides black level clamping for an accurate black level reference, input signal clamping, and offset correction of the CDS. The VSP2254 operates from 2.7 V to 3.6 V of single supply.
