FEATURES  
DESCRIPTIO  
The LTC®1565-31 is a 7th order, continuous time, linear  
phase lowpass filter. The selectivity of the LTC1565-31,  
combined with its linear phase and dynamic range, make it  
suitable for filtering in data communications or data acqui-  
sition systems. The filter attenuation is 37dB at 2× fCUTOFF  
and at least 72dB for frequencies above 3× fCUTOFF. Unlike  
comparable LC filters, the LTC1565-31 achieves this selec-  
tivity with a linear phase response in the passband.
