Overview
U U LTC1064-2 Low Noise, High Frequency, 8th Order Butterworth Lowpass Filter FEATURES ■ 8th Order Filter in a 14-Pin Package ■ 140kHz Maximum Corner Frequency ■ No External Components ■ 50:1 and 100:1 Clock to Cutoff Frequency Ratio ■ 80µVRMS Total Wideband Noise ■ 0.
03% THD or Better ■ Operates from ±2.
37V to ±8V Power Supplies U APPLICATIO S ■ Antialiasing Filters ■ Smoothing Filters ■ Tracking High Frequency Lowpass Filters DESCRIPTIO 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 LTC1064...
