LM9800  
8-Bit Greyscale/24-Bit Color Linear CCD Sensor  
Processor  
General Description  
Features  
n 2.5 million pixels/s conversion rate  
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 conver-  
sion) necessary to maximize the performance of a wide  
range of linear CCD sensors.  
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  
The LM9800 can be digitally programmed to work with a  
wide variety of CCDs from different manufacturers. An inter-  
nal configuration register sets CCD and sampling timing to  
maximize performance, simplifying the design and manufac-  
turing 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 comple-  
mentary voltage reference see the LM4041.
