FEATURES  
DESCRIPTION  
TheLT®6604-2.5consistsoftwomatched,fullydifferential  
amplifiers,eachwitha4thorder,2.5MHzlowpasslter.The  
fixed frequency lowpass filter approximates a Chebyshev  
response. By integrating a filter and a differential ampli-  
fier, distortion and noise are made exceptionally low. At  
unity gain, the measured in-band signal-to-noise ratio is  
an impressive 86dB. At higher gains, the input referred  
noise decreases, allowing the part to process smaller  
input differential signals without significantly degrading  
the signal-to-noise ratio.

Fully Differential Inputs and Outputs  
Gain and phase are well matched between the two chan-  
nels. Gain for each channel is independently programmed  
usingtwoexternalresistors. TheLT6604-2.5enableslevel  
shifting by providing an adjustable output common mode  
voltage, making it ideal for directly interfacing to ADCs.  
The LT6604-2.5 is fully specified for 3V operation. The  
differential design enables outstanding performance up
