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
