CXA2027Q

Analog signal processor IC

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.)
