LTC1064-2CN#PBF Datasheet PDF - Linear Technology

●The LTC1064-2CN#PBF is a monolithic 8th Order Butterworth Lowpass 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 LTC1064-2 overall performance competes with equivalent multiple op amp RC active realizations.
