CXA1310AQ
Single Chip Processing for CCD Monochrome Camera
Description The CXA1310AQ is designed to perform the basic signal processing in CCD monochrome cameras with a single chip. This bipolar lC is most suitable for compact usage and low power consumption. Features • Processing from CCD output to 75Ω video output with a single chip • Wide variable AGC (4 to 32dB Typ.) • Built-in operational amplifier for AGC loop • 75Ω line capacitance minimized using sag compensation fun.
