LTC1064-3

U U LTC1064-3 Low Noise, High Frequency, 8th Order Linear Phase Lowpass Filter FEATURES ■ 8th Order Filter in a 14-Pin Package ■ 95kHz Maximum Corner Frequency ■ No External Components ■ 75:1, 150:1 and 120:1 Clock to Cutoff Frequency Ratio ■ 60µVRMS Total Wideband Noise ■ 0.03% THD or Better ■ Operates from ±2.37V to ±8V Power Supplies ■ Low Total Output DC Offset U APPLICATIO S ■ Antialiasing Filters ■ Smoothing Filters ■ Tracking High Frequency Lowpass Filters DESCRIPTIO The LTC®1064-3 is a monolithic 8th order lowpass Bessel filter, which provides a linear phase response over its entire passband. An external TTL or CMOS clock programs the filter’s cutoff frequency. The clock to cutoff frequency ratio is 75:1 (Pin 10 at V+) or 150:1 (Pin 10 at V–) or 120:1 (Pin 10 at GND). The maximum cutoff frequency is 95kHz. No external components are needed. The LTC1064-3 features low wideband noise and low harmonic distortion even for input voltages up to 3VRMS....
