TMUX1108: What does the On and Off capacitance mean?
Part Number: TMUX1108
In the datasheet, the test condition of cson/cdon parameter is 1Mhz；
will the capacitance varies with the signal frequency, if yes how is the relationship.
Thanks for using e2e. The On Capacitance of a mux does affect the mux bandwidth - See below relationship explaining how low On Capacitance can help achieve higher bandwidth.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Saminah C:
What I realy want to know is would the port capacitance(cson/cdon) varies with signal frequency?
In reply to user6041007:
No, the capacitance for the switch is fixed and does not very with the signal frequency..
The above relationship just shows when you are designing a switch, how to achieve higher bandwidth by lowering the On capacitance.
thank you very much.
It helps a lot.
