The ADCDS-1410 is an application-specific video signal processor designed for
electronic-imaging applications that employ CCD's (charge coupled devices) as their
photodetector. The ADCDS-1410 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-1410'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-1410 digitizes this resultant "valid video" signal using a high-speed, low-noise
sampling A/D converter.
The ADCDS-1410 requires only the rising edge of start convert pulse to initiate its con-
version process. Additional features of the ADCDS-1410 include gain adjust, offset adjust,
precision +2.4V reference, and a programmable analog bandwidth function.
