LTC1064-7 - Linear Phase, 8th Order Lowpass Filter

The LTC1064-7 features wide dynamic range. With single 5V supply, the S/N + THD is 76dB. Optimum 92dB S/N is obtained with ±7.5V supplies. The clock-to-cutoff frequency ratio of the LTC1064-7 can be set to 50:1 (pin 10 to V + ) or 100:1 (pin 10 to V - ).

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

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