PRODUCT OVERVIEW

The CDS-1402 is an application-specif c, correlated double sampling (CDS) circuit designed for electronic-imaging applications that employ CCDs (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 pixels true video signal level by sequentially sampling the pixels offset signal and its video signal and subtracting the two. The result is that the consequences of residual charge, charge injection and low-frequency kTC noise on the CCDs output ? oating capacitor are effectively eliminated. The CDS-1402 can also be used as a dual sample-hold amplif er in a data acquisition system.
