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.

Key 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 increments for maximum performance n Generates all necessary CCD clock signals n Compatible with a wide range of linear CCDs n TTL/CMOS input/output compatible Key Specifications n Resolution n Pixel.
