LM9800 8-Bit Greyscale/24-Bit Color Linear CCD Sensor Processor September 1997 LM9800 8-Bit Greyscale/24-Bit Color Linear CCD Sensor Processor General Description The LM9800 is a high performance integrated signal processor/digitizer for linear CCD image scanners. The LM9800 performs all the analog processing (correlated double sampling for black level and offset compensation, pixel-by-pixel gain adjust, and 8-bit analog-to-digital conversion) necessary to maximize the performance of a wide range of linear CCD sensors. The LM9800 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.
