4051 and the likes have a resistance that varies with the applied signal voltage. If you don't object to phase inverson, - using an opamp as an inverting amp- try to use the mux part inside a summing/current amp - mux output directly couples to the - input, and choose series and feedback resistors to match your impedance and gain demands.

The Mux or Switch RDSON matters in systems where the devices are used in precision applications, few examples: ADC sampling (RC impact), Feedback loop for gain adjustments (RDSON and RDSON between channels matter) or audio systems with impedance control.

standard devices: the CD4016, CD4066, CD4051, CD4052, CD4053. The first two devices are quad bilateral switches that can pass audio or digital either The 4016 can fade audio because there are no gates or buffers on the control pin. 4066 has a buffered gate and will hard switch. The 4051, 4052, 4053 are mux
