LTC1164-6 Low Power 8th Order Pin Selectable Elliptic or Linear Phase Lowpass Filter DESCRIPTIO FEATURES 8th Order Pin Selectable Elliptic or Bessel Filter in a The LTC1164-6 is a monolithic 8th order elliptic lowpass 14-Pin Package filter featuring clock-tunable cutoff frequency and low 4mA Supply Current with ±5V Supplies power supply current. Low power operation is achieved 64dB Attenuation at 1.44 fCUTOFF (Elliptic Response) without compromising noise or distortion performance. fCUTOFF up to 30kHz (50:1 fCLK to fCUTOFF Ratio) At ±5V supplies the LTC1164-6 uses only 4mA supply 110µVRMS Wideband Noise with ±5V Supplies current while keeping wideband noise below 110µVRMS. Operates at Single 5V Supply with 1VRMS With a single 5V supply, the LTC1164-6 can provide up to Input Ra
