LTC1064-2

The LTC^®1064-2 is a monolithic 8th order lowpass Butterworth filter, which provides a maximally flat passband. 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.

The LTC1064-2 features low wideband noise and low harmonic distortion even for input voltages up to 3VRMS. In fact the device 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.
