Description
The CXA1690Q is a bipolar IC developed as a head amplifier for digital CCD cameras. The CXA1690Q provides the following functions: correlated double sampling, AGC for CCD signals, GCA for chroma signals, GCA for line signals, sample and hold for A/D converters, blanking, and reference voltage output/output driver for A/D converters.

FEATUREs
• Permits higher sensitivity with a high-gain AGC amplifier
• Blanking function for the purpose of calibrating the deviation in black levels of the CCD output signals
• Permits output offset adjustment
• Provides a regulator output pin for the reference voltage for A/D converters
• Built-in GCA that amplifies video signals (chroma and line signals) from an external source
• Built-in sample-and-hold circuits (for both camera signals and video signals) required by external A/D converters

APPLICATIONs
    Digital CCD cameras
