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