DESCRIPTIO

The LTC

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

is 140kHz. No external components are needed.

The LTC1064-2 features low wideband noise and low

harmonic distortion even for input voltages up to 3V

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.

The LTC1064-2 is pin compatible with the LTC1064-1.
