The LTC1064-1 is an 8th order, clock sweepable elliptic (Cauer) lowpass switched capacitor filter designed for applications such as antialiasing filters and telecom PCM filters. It features a passband ripple of typically +0.15dB and stopband attenuation of 68dB or more at 1.5 times the cutoff frequency. The device operates from +2.37V to +8V power supplies and requires no external components for cutoff frequencies up to 20kHz.
