DESCRIPTIO  
EATURE

F
The LTC1164-6 is a monolithic 8th order elliptic lowpass  
filter featuring clock-tunable cutoff frequency and low  
power supply current. Low power operation is achieved  
without compromising noise or distortion performance.  
At ±5V supplies the LTC1164-6 uses only 4mA supply  
8th Order Pin Selectable Elliptic or Bessel Filter in a  
14-Pin Package  
4mA Supply Current with ±5V Supplies  
64dB Attenuation at 1.44 fCUTOFF (Elliptic Response)  
fCUTOFF up to 30kHz (50:1 fCLK to fCUTOFF Ratio)

current while keeping wideband noise below 110µVRMS  
.
With a single 5V supply, the LTC1164-6 can provide up to  
10kHz cutoff frequency and 80dB signal-to-noise ratio  
while consuming only 2.5mA.  
The LTC1164-6 provides an elliptic lowpass rolloff with  
stopband attenuation of 64dB at 1.44 fCUTOFF and an fCLK  
-
to-fCUTOFF ratioof100:1(pin10toV).Foraratioof100:1,  
fCUTOFF can be clock-tuned up to 10kHz. For a fCLK-to-  
fCUTOFF ratio of 50:1 (pin 10 to V+), the LTC1164-6  
provides an elliptic lowpass filter with fCUTOFF frequencies  
up to 20kHz. When pin 10 is connected to ground, the  
LTC1164-6 approximates an 8th order linear phase re-  
sponse with 65dB attenuation at 4.5 f3dB and fCLK/f3dB  
ratio of 160:1. The LTC1164-6 is pin compatible with the  
LTC1064-1.
