LTC1164-7 - Low Power, Linear Phase 8th Order Lowpass Filter

Low power is achieved without sacrificing dynamic range. With single 5V supply, the S/N + THD is up to 75dB. Optimum 91dB S/N is obtained with ±7.5V supplies.

The clock-to-cutoff frequency ratio of the LTC1164-7 can be set to 50:1 (pin 10 to V + ) or 100:1 (pin 10 to V - ).

When the filter operates at the clock-to-cutoff frequency ratio of 50:1, the input is double-sampled to lower the risk of aliasing.

The LTC1164-7 is pin-compatible with the LTC1064-X series and LTC1264-7.
