DESCRIPTION
The LTC®1164-6 is a monolithic 8th order elliptic lowpass filter featuring clock-tunable cutoff frequency and low power supply current. Low power operation is achieved without compromising noise or distortion performance. At ±5V supplies the LTC1164-6 uses only 4mA supply current while keeping wideband noise below 110µVRMS. With a single 5V supply, the LTC1164-6 can provide up to 10kHz cutoff frequency and 80dB signal-to-noise ratio while consuming only 2.5mA.
