For the availability of this product, please contact the sales office.
Description
The CXA2027Q is an analog signal processor for
48 pin QFP (Plastic)
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
Absolute Maximum Ratings
are recommended as AD converters.)
