LM9801 - 8-Bit Greyscale/24-Bit Color Linear CCD Sensor Processor
The LM9801 is a high performance integrated signal processor digitizer for linear CCD image scanners The LM9801 performs all the analog processing (correlated double sampling for black level and offset compensation pixel-by-pixel gain (shading) correction and 8-bit analog-to-digital conversion) nece
LM9801 Features
* Y 2 5 Million pixels s conversion rate Y Pixel-rate shading correction for individual pixels maxi- mizes dynamic range and resolution even on ‘‘weak’’ pixels Y Implements Correlated Double Sampling for minimum noise and offset error Y Reference and signal sampling points digitally controlled in 25 n
