LTC1064-4CSW

Low noise, 8-order, clock Sweepable elliptical low-pass filter

peculiarity An 8th order filter in a 14-pin package No external components are required Center ratio 100:1 clock 150μVRMS total wideband noise Total harmonic distortion of 0.03% or better Maximum angular frequency of 50kHz Power supplies from ± 2.37V to ± 8V Guaranteed passband ripple over the entire military temperature range description The LTC ® 1064-1 is an 8-order, clock-sweepable elliptical (Kaul) low-pass switched capacitive filter. Passband ripple typically ± 0.15 dB with stopband attenuation at 1.5 times the cut-off frequency of 68 dB or more. Cut-off frequency values for external TTL or CMOS clock scheme filters. The cut-off frequency ratio clock is 100:1. Cut-off frequencies of up to 20 kHz are required without external components. The passband flatness must be maintained for both low capacitance values with cut-off frequencies above 20kHz. LTC1064-1 has low wideband noise and low harmonic distortion, even up to 3V RMS to input voltages. In fact, the overall performance of the LTC1064-1 is equivalent to the RC active implementation of multiple op-amps. LTC1064-1 is a SW package that is surface mounted on a 14-pin DIP or 16-pin surface. Pin LTC1064 - 1, LTC1064 - 2 is compatible.
