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. The AD9802 is packaged in a space saving 48-terminal thin quad flatpack (TQFP) and is specified over an operating temperature range of 0C to +70C.
