DESCRIPTIO The LTC®1064-4 is an 8th order, clock sweepable Cauer lowpass switched capacitor filter.
An external TTL or CMOS clock programs the value of the filter’s cutoff frequency.
With Pin 10 at V+, the fCLK to fCUTOFF ratio is 50:1; the filter has a Cauer response and with compensation the passband ripple is ±0.
1dB.
