GENERAL DESCRIPTION
The ADCDS-1403 is an application-specific video signal
processor designed for electronic-imaging applications that
employ CCD's (charge coupled devices) as their
photodetector. The ADCDS-1403 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-1403'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-1403 digitizes this resultant
"valid video" signal using a high-speed, low-noise sampling
A/D converter.
The ADCDS-1403 requires only the rising edge of start
convert pulse to initiate its conversion process. Additional
features of the ADCDS-1403 include gain adjust, offset
adjust, precision +2.4V reference, and a programmable
analog bandwidth function.
