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
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
脳
3 lines/5363 pixels
脳
3 lines/7078 pixels
