LTC1164-5 Low Power 8th Order Pin Selectable Butterworth or Bessel Lowpass Filter DESCRIPTIO FEATURES Pin Selectable Butterworth or Bessel Response The LTC®1164-5 is a monolithic 8th order filter; it approxi- 4mA Supply Current with ±5V Supplies mates either a Butterworth or a Bessel lowpass response. fCUTOFF up to 20kHz The LTC1164-5 features clock-tunable cutoff frequency 100µVRMS Wideband Noise and low power consumption (4.5mA with ±5V supplies THD < 0.02% (50:1, VS = ±7.5V, VIN = 2VRMS) and 2.5mA with single 5V supply). Operates with a Single 5V Supply (1VRMS Input Low power operation is achieved without compromising Range) noise or distortion performance. With ±5V supplies and 60µVRMS Clock Feedthrough (Single 5V Supply) 10kHz cutoff frequency, the operating signal-to
