PRODUCTION DESCRIPTION

The AD9807 and AD9805 are complete CCD/CIS imaging decoders and signal processors on a single monolithic integrated circuit. The input of the AD9807/AD9805 allows direct ac coupling of the charge-coupled device (CCD) or contact image sensor (CIS) output(s). The AD9807/AD9805 includes all the circuitry to perform three-channel correlated double sampling (CDS) and programmable gain adjustment of the CCD output; a 12-bit or 10-bit analog-to-digital converter (ADC) quantizes the analog signal. After digitization, the on-board digital signal processor (DSP) circuitry allows pixel rate offset and gain correction. The DSP also corrects odd/even CCD register imbalance errors.
