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
V
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.
