LTC1064-1CN

Active Filter Single SW-CAP Low Pass 8th Order 50kHz 14Pin PDIP N

DESCRIPTION

The LTC®1064-1 is an 8th order, clock sweepable elliptic Cauer lowpass switched capacitor filter. The passband ripple is typically ±0.15dB, and the stopband attenuationat 1.5 times the cutoff frequency is 68dB or more. An external TTL or CMOS clock programs the value of the filter’s cutoff frequency. The clock to cutoff frequency ratio is 100:1.
