CXA1690Q 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.
CXA1690Q Key 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
