LT6600-2.5  
Very Low Noise, Differential  
Amplifier and 2.5MHz Lowpass Filter  
FEATURES  
DESCRIPTION  
The LT®6600-2.5 combines a fully differential amplifier  
with a 4th order 2.5MHz lowpass filter approximating a  
Chebyshev frequency response. Most differential ampli-  
fiers require many precision external components to tail  
or gain and bandwidth. In contrast, with the LT6600-2.5,  
two external resistors program differential gain, and the  
filter’s 2.5MHz cutoff frequency and passband ripple are  
internallyset. TheLT6600-2.5alsoprovidesthenecessary

Using a proprietary internal architecture, the LT6600-2.5  
integrates an antialiasing filter and a differential ampli-  
fier/driver without compromising distortion or low noise  
performance. At unity gain the measured in band signal-  
to-noise ratio is an impressive 86dB. At higher gains the  
input referred noise decreases so the part can process  
smaller input differential signals without significantly  
degrading the output signal-to-noise ratio.
