LM9811
10-Bit Greyscale/30-Bit Color
Linear CCD Sensor Processor
General Description
The LM9811 is a high performance integrated signal
processor/digitizer for linear CCD image scanners. The
LM9811 performs all the analog processing (correlated
double sampling for black level and offset compensation,
pixel-by-pixel
gain
(shading)
analog-to-digital conversion) necessary to maximize the per-
formance of a wide range of linear CCD sensors.
The LM9811 can be digitally programmed to work with a
wide variety of CCDs from different manufacturers. An inter-
nal configuration register sets CCD and sampling timing to
maximize performance, simplifying the design and manufac-
turing processes.
The LM9811 can be used with parallel output color CCDs. A
signal inversion mode eases use with CIS sensors. For
complementary voltage reference see the LM4041.
