The LTC1164-6 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. The LTC1164-6 provides an elliptic lowpass rolloff with stopband attenuation of 64dB at 1.44 fCUTOFF and an fCLK-to- fCUTOFF ratio of 100:1 (Pin10 to V– ). For a ratio of 100:1, fCUTOFF can be clock-tuned up to 10kHz. For a fCLK-to-fCUTOFF ratio of 50:1 (Pin 10 to V+ ), the LTC1164-6 provides an elliptic lowpass filter with fCUTOFF frequencies up to 20kHz. When Pin 10 is connected to ground, the LTC1164-6 approximates an 8th order linear phase response with 65dB attenuation at 4.5 f–3dB and fCLK/f–3dB ratio of 160:1. The LTC1164-6 is pin compatible with the LTC1064-1.
