The LTC1064-4 is an 8th order, clock sweepable Cauer low-pass switched capacitor filter designed for applications such as antialiasing filters, telecom filters, and sinewave generators. An external TTL or CMOS clock programs the value of the filter's cutoff frequency.
The device features low noise (135µVrms total wideband noise) and low harmonic distortion (0.03% THD). It operates with power supplies up to +8V and supports input frequencies up to 50 times the filter cutoff frequency. The LTC1064-4 is pin compatible with the LTC1064-1, LTC1064-2, and LTC1064-3.
