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....
