IC_filter_with_programmed_cutoff_frequencies
This circuit shows an LTC1062 used with a dual four-channel MUX (74HC4052) and an LT311 to provide four different cutoff frequencies (500, 250, 125, and 62.5 Hz). Notice that the clock frequency and the external R×C product are varied simultaneously so that: 1/(6.28RC) =fc/1.64=fclock/1.64. Linear Technology Corporation, Linear Applications Handbook, 1992, p.
