The AD9802 includes a low-noise, wideband amplifier with analog variable gain from 0 dB to 31.5 dB (linear in dB). The AD9802 is a complete CCD signal processor developed for electronic cameras. It is suitable for both camcorder and consumer-level still camera applications.

The signal processing chain is comprised of a high speed CDS, variable gain PGA and 10-bit ADC. Required clamping circuitry and an onboard voltage reference are provided as well as a direct ADC input. The AD9802 operates from a single +3 V supply with a typical power consumption of 185 mW.
