LM9800 Datasheet (National Semiconductor) - 8-Bit Greyscale/24-Bit Color Linear CCD Sensor Processor

LM9800, 8-Bit Greyscale/24-Bit Color Linear CCD Sensor Processor

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 ma

LM9800 Features

* n 2.5 million pixels/s conversion rate n Implements Correlated Double Sampling for minimum noise and offset error n Pixel-to-pixel gain correction for individual pixels maximizes dynamic range and resolution, even on “weak” pixels n Reference and signal sampling points digitally controlled in 25ns i
