LM9801 8-Bit Greyscale 24-Bit Color Linear
CCD Sensor Processor
General Description
The LM9801 is a high performance integrated signal proc-
essor digitizer for linear CCD image scanners The LM9801
performs all the analog processing (correlated double sam-
pling for black level and offset compensation pixel-by-pixel
gain (shading) correction and 8-bit analog-to-digital conver-
sion) necessary to maximize the performance of a wide
range of linear CCD sensors
The LM9801 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 LM9801 can be used with parallel output color CCDs A
signal inversion mode eases use with CIS sensors For com-
plementary voltage reference see the LM4041
