    Default CD4051 analog multiplexer crosstalk

    Had anyone experienced any problems on using CD4051 analog multiplexer regarding crosstalk? Is there a relation between the supply voltage with the crosstalk?

    I use 5 volt supply for it. And inputs on the CD4051 ranges from 0 to 5V linear.

    Any suggestions??

    Use a lower impedance (and therefore more distortion) on the inputs of the "receiving" circuits, or use more multiplexers to switch the unselected receiving circuits to a low impedance idle voltage.
