FEATURES  
DESCRIPTION  
The LM98714 is a fully integrated, high performance  
16-Bit, 45 MSPS signal processing solution for digital  
color copiers, scanners, and other image processing  
applications. High-speed signal throughput is  
achieved with an innovative architecture utilizing  
Correlated Double Sampling (CDS), typically  
employed with CCD arrays, or Sample and Hold  
(S/H) inputs (for Contact Image Sensors and CMOS

image sensors). The signal paths utilize  
8 bit  
Digital Black Level Correction Loop for Each  
Channel  
Programmable Gain Amplifiers (PGA), a +/-9-Bit  
offset correction DAC and independently controlled  
Digital Black Level correction loops for each input.  
The PGA and offset DAC are programmed  
independently allowing unique values of gain and  
offset for each of the three inputs. The signals are  
then routed to a 45MHz high performance analog-to-  
digital converter (ADC). The fully differential  
processing channel shows exceptional noise  
immunity, having a very low noise floor of -74dB. The  
16-bit ADC has excellent dynamic performance  
making the LM98714 transparent in the image  
reproduction chain.
