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) correction, and 10-bit analog-to-digital conversion) necessary to maximize the performance 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 internal configuration register sets CCD and sampling timing to maximize performance, simplifying the design and manufacturing 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.
