FEATURES  
DESCRIPTIO  
The LTC®1064-2 is a monolithic 8th order lowpass  
Butterworth filter, which provides a maximally flat pass-  
band. The attenuation slope is –48dB/octave and the  
maximum attenuation is in excess of 80db. An external  
TTL or CMOS clock programs the filter’s cutoff frequency.  
The clock to cutoff frequency ratio is 100:1 (Pin 10 at  
V) or 50:1 (Pin 10 at V+). The maximum cutoff frequency  
is 140kHz. No external components are needed.

U
The LTC1064-2 features low wideband noise and low  
harmonic distortion even for input voltages up to 3VRMS  
In fact the LTC1064-2 overall performance competes with  
equivalent multiple op amp RC active realizations. The  
LTC1064-2 is available in a 14-pin DIP or 16-pin surface  
mounted SW package. The LTC1064-2 is fabricated using  
LTC’s enhanced analog CMOS Si-gate process.
