Description
The CXA2027Q is an analog signal processor for CCD linear image sensor output signal. This device is suitable for 3 lines of full-color CCD linear image sensor (ILX516K/ILX518K/ILX520K: 3648 pixels × 3 lines/5363 pixels × 3 lines/7078 pixels × 3 lines). This device has a built-in sample-and-hold, clamp, multiplex, gain control amplifier circuits and can be connected directly with external AD converters. (Sony’s CXD2311AR, CXD1175AM or CXA1977R are recommended as AD converters.)

FEATUREs
• Sample-and-hold circuit
• Pixel-clamp and line-clamp circuit
• Multiplex circuit
• ADC driver circuit
• Gain control amplifier circuit
• Offset control circuit
• Clock frequency: 1.5 to 6MHz (after multiplex)

APPLICATIONs
    Color image scanner
