Cutting good performance signal switching circuit

Analog switches sl and sa disconnect, Ctz the inverted logic signal to terminal 2 s! And 84 is turned on, so that prisoners capacitance between S1 and S 8 and coupling will be

generated and S 2 and 8 4 shunt (on-state resistance 50 ~ lOOQ). OP buffer amplifier is a buffer amplifier. Rz need to choose according to the availability of several scrimp 4 1 +/l where the voltage gain.
