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.

An internal configuration register sets CCD and sampling timing to maximize performance, simplifying the design and manufacturing processes. 

The LM9800 can be used with sequential or parallel output color CCDs. Coarse gain switching brings weak Blue signals up to Red/Green levels for best performance. For complementary voltage reference see the LM4041.
