CXA1690Q Datasheet | Sony Semiconductor Solutions

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 m W VCC1, 2, 3 4.5 to 5 Sony reserves the right to change products and specifications without prior notice.
