The ADCDS-1603 incorporates a "user configurable" input amplifier, a CDS (correlated double sampler) and a 16-bit resolution 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-1603'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 pixel data output signal. The ADCDS-1603 digitizes this resultant pixel data signal using a high-speed, low-noise sampling A/D converter. The ADCDS-1603 requires only the rising edge of start convert pulse to initiate its conversion process and a Reference Hold command to acquire and hold the CCD reference level output. Additional features of the ADCDS-1603 include gain adjust, offset adjust, precision +2.048V reference, and a programmable analog bandwidth function.
