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.)
