CCD Signal Processor Designed For Digital Cameras

On-board clamping circuitry, programmable gain amplifier, and voltage reference all help make the AD9803 CCD and video signal processor easy to design into electronic camera circuits, as well as video and still-cameras. The device features an 18-MHz correlated double sampler, low-noise, programmable gain amplifier with 0 to 30-dB gain range, black level correction circuit, and a 10-bit, 18-MHz A/D converter. It operates from a 3V supply and consumes just 180 mW. Packaged in a 48-pin LQFP, the device is specified over an operating temperature range of -20°C to 75°C.
