LM9812 30-Bit Color Linear CCD Sensor Processor December 1997 LM9812 30-Bit Color Linear CCD Sensor Processor General Description The LM9812 is a high performance integrated signal processor/digitizer for color linear CCD image scanners. The LM9812 performs all the signal processing (correlated double sampling, pixel rate offset and shading correction, color balance control, and 10-bit analog-to-digital conversion) necessary to maximize the performance of a wide range of linear CCD sensors. The LM9812 can be digitally programmed to work with a wide variety of CCDs from different manufacturers, including both 3 output RGB and 2 output GRGB CCDs. An internal Configuration Register sets CCD and sampling timing to maximize performance, simplifying the design and manufacturing processes. For plementary voltage reference see the LM4041-ADJ.
