... The result is that the consequences of residual charge, charge injection and low-frequency "kTC" noise on the CCD's output floating capacitor are effectively eliminated. The CDS-1402 can also be used as a dual sample-hold amplifier in a data acquisition system. The CDS-1402 contains two sample-hold amplifiers and appropriate support/control circuitry ...

... Funtional Description ), the circuit actually exploits an elegant architecture whose tradeoffs enable it to offer wide-bandwidth, low-noise and high-throughput combinations unachievable until now. The CDS-1402, a generic type of circuit, can be used with most 10 to 14-bit A/D converters. However, DATEL offers A/D converters optimized for use with CDS-1402. ...

... The DATEL CDS-1402 takes a slightly different, though clearly superior, approach to CDS. It can be called the "sample- subtract-sample" approach. Note that the CDS-1402 has been configured to offer the greatest amount of user flexibility. Its two S/H circuits function independently. They have separate input and output pins. ...
