LTC1064-4CJ Datasheet PDF - Linear Technology

DESCRIPTION
The LTC®1064-4 is an 8th order, clock sweepable Cauer lowpass switched capacitor filter. An external TTL or CMOS clock programs the value of the filter’s cutoff frequency.

FEATURES
■ 8th Order Filter in a 14-Pin Package
■ 80dB or More Stopband Attenuation at 2 × fCUTOFF
■ 50:1, fCLK to fCUTOFF Ratio (Cauer) 100:1, fCLK to f–3dB Ratio (Transitional)
■ 135µVRMS Total Wideband Noise
■ 0.03% THD or Better
■ 100kHz Maximum fCUTOFF Frequency
■ Operates up to ±8V Power Supplies
■ Input Frequency Range up to 50 Times the Filter Cutoff Frequency

APPLICATIONS
■ Antialiasing Filters
■ Telecom Filters
■ Sinewave Generators
