LTC1069-6  
Single Supply, Very Low  
Power, Elliptic Lowpass Filter  
FEATURES  
DESCRIPTION  
TheLTC®1069-6isamonolithiclowpower,8thorderlowpass  
filter optimized for single 3V or single 5V supply operation.  
The LTC1069-6 typically consumes 1mA under single 3V  
supply operation and 1.2mA under 5V operation.

CUTOFF  
ThecutofffrequencyoftheLTC1069-6isclocktunableanditis  
equal to the clock frequency divided by 50. The input signal is  
sampled twice per clock cycle to lower the risk of aliasing.
