CXA2056Q
Digital CCD Camera Head Amplifier
Description
The CXA2056Q is a bipolar IC developed as a
head amplifier for digital CCD cameras. This IC
provides the following functions: correlated double
sampling, AGC for the CCD signal, GCA for the low-
band chroma signal, AMP for high-band chroma and
line signals, A/D sample and hold, blanking, A/D
reference voltage, and an output driver.
Features
• High sensitivity made possible by a high-gain AGC
amplifier
• Blanking function provided for the purpose of
calibrating the CCD output signal black level
• Regulator output pin provided for A/D converter
reference voltage
• Built-in GCA and AMP for amplifying video signals
(chroma and line signals) from external sources
• Built-in sample-and-hold circuits for camera signals
required by external A/D converters
Absolute Maximum Ratings

• Operating temperature Topr
• Storage temperature Tstg
