Shunt-switched bandpass filter with o of 1000 and voltage gain of about 7 uses DG508 CMOS multiplexer containing required analog switches,interface cicuhs, and deoode logic for 8-path filter. Bandwidth for 3 dB down is 1 Hz centered on 1 kHz, with asymptotic slope of 6 dB per octave. Clock controls shunt-switched filter action.- Analog switches and Their Applications, Siliconix,Santa Clara,CA,1976,p 5-12-5-14.
