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. A parallel control bus provides a simple interface to 8-bit microcontrollers.
The AD9807/AD9805 comes in a space saving 64-pin plastic quad flatpack (PQFP) and is specified over the commercial (0°C to +70°C) temperature range. By disabling the CDS, the AD9807/AD9805 are also suitable for non-CCD applications, or applications that do not require CDS, such as CIS signal processing.
