CXA1690Q

CXA1690Q Head Amplifier for Digital CCD Cameras 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 Absolute Maximum Ratings Supply voltage Operating temperature Storage temperature Allowable power dissipation Operating Conditions Supply voltage 32 pin QFP (Plastic) Structure Bipolar silicon monolithic IC Applications Digital CCD cameras VCC Topr Tstg PD 14 V –20 to +75 °C –65 to +150 °C 460 mW VCC1, 2, 3 4.5 to 5 V Sony reserves the right to change products and specifications without prior notice.
