LM9811 Datasheet (National Semiconductor) - 10-Bit Greyscale/30-Bit Color Linear CCD Sensor Processor

LM9811, 10-Bit Greyscale/30-Bit Color Linear CCD Sensor Processor

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)

LM9811 Features

* n 1.5 Million pixels/s conversion rate n Pixel-rate shading correction for individual pixels maximizes dynamic range and resolution, even on “weak” pixels n Implements Correlated Double Sampling for minimum noise and offset error n Reference and signal sampling points digitally controlled in 40ns in
