20dB at 1.2fCUTOFF  
The cutoff frequency (fCUTOFF) of the LTC1069-1 is equal  
to the clock frequency divided by 100. The gain at fCUTOFF  
is 0.7dB and the typical passband ripple is ±0.15dB  
up to 0.9fCUTOFF. The stopband attenuation of the  
LTC1069-1 features a progressive elliptic response

With ±5V supplies, the LTC1069-1 cutoff frequency can  
be clock-tuned up to 12kHz; with a single 5V supply, the  
maximum cutoff frequency is 8kHz.
