PRODUCT DESCRIPTION

The AD9803 is a complete CCD and video signal processor developed for electronic cameras. It is well suited for video camera and still-camera applications.

The 18 MHz CCD signal processing chain consists of a CDS, low noise PGA, and 10-bit ADC. Required clamping circuitry and a voltage reference are also provided. The AUX input features a wideband PGA and input clamp, and can be used to sample analog video signals.

The AD9803 nominally operates from a single 3 V power supply, typically dissipating 170 mW. The AD9803 is packaged in a space-saving 48-lead LQFP and is specified over an operating temperature range of –20°C to +70°C.
