LTC1164-6 Low Power 8th Order Pin Selectable Elliptic or Linear Phase Lowpass Filter FEATURES DESCRIPTIO 8th Order Pin Selectable Elliptic or Bessel Filter The LTC 1164-6 is a monolithic 8th order elliptic lowpass 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 f (Elliptic Response) CUTOFF f Up to 30kHz (50:1 f to f Ratio) without compromising noise or distortion performance. CUTOFF CLK CUTOFF At 5V supplies the LTC1164-6 uses only 4mA supply 110V Wideband Noise with 5V Supplies RMS current while keeping wideband noise below 110V . Operates at Single 5V Supply with 1V RMS RMS Input Range With a single 5V supply, the LTC1164-6 can provide up to 10kHz cutoff frequency and 80dB signal-to-noise ratio Operates Up to 8V Supplies while consuming only 2.5mA. TTL/CMOS Compatible Clock Input No External Components The LTC1164-6 provides an elliptic lowpass rolloff with Available in 14-Pin Dip and 16-Pin SO Wide Packages stopband attenuation of 64dB at 1.44 f and an f - CUTOFF CLK ratio of 100:1 (Pin 10 to V ). For a ratio of 100:1, to-f CUTOFF U f can be clock-tuned up to 10kHz. For a f -to- CUTOFF CLK APPLICATIO S + f ratio of 50:1 (Pin 10 to V ), the LTC1164-6 CUTOFF Antialiasing Filters frequencies provides an elliptic lowpass filter with f CUTOFF Battery-Operated Instruments up to 20kHz. When Pin 10 is connected to ground, the Telecommunication Filters LTC1164-6 approximates an 8th order linear phase re- and f /f sponse with 65dB attenuation at 4.5 f 3dB CLK 3dB ratio of 160:1. The LTC1164-6 is pin compatible with the LTC1064-1. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners.
