LTC1064-2CSW#PBF

LTC1064-2 is a monolithic 8th order low pass butterworth filter, which provides a maximally flat passband. The attenuation slope is -48dB/octave and the maximum attenuation is in excess of 80db. An external TTL or CMOS clock programs the filter’s cut-off frequency. The clock to cut-off frequency ratio is 100:1 (pin 10 at V-) or 50:1 (pin 10 at V+). This device features low wideband noise and low harmonic distortion even for input voltages upto 3VRMS. In fact the device overall performance competes with equivalent multiple op-amp RC active realizations. It is widely used in application such as antialiasing filters, smoothing filters, tracking high frequency low pass filters etc.

• 140KHz maximum corner frequency, no external components

• Total harmonic distortion is 0.03% typical at (VS = ±7.5V, Input = 3VRMS at 1KHz)
• Power supply voltage range is ±2.37V to ±8V
• Power supply current is 11mA typical at (VS = ±2.37V, fCLK = 1MHz)
• Gain tempCo is 0.0002dB/°C typical
• 20KHz typical -3dB frequency
• Operating temperature is -40°C to 85°C
• Package style is 16-lead WSOIC
