Thanks for the quick response. &nbsp;i was thinking something like the 4066 or 4016 would also work.

I have a circuit that has several different capacitors in it that I am currently using SP3T switch to switch between the capacitors. &nbsp;They are in a 555 timer circuit and the various capacitors change the output according to which capacitor is connected. &nbsp;I have 3 non-polarized on a switch and 3 polarized on another switch. &nbsp;What I want to do is eliminate the manual switches and replace them with an ic switch so I can choose which cap is connected to the circuit using a micro. &nbsp;I'm not sure what kind of ic would be appropriate for this type of application. &nbsp;I found this ic TS5A3357 I am thinking about getting and trying. &nbsp;I would like to know if anyone has a suggestion or can tell me if the ic will work. &nbsp;I'm sure I could use reed relays for this, but I would rather use an ic switch if possible. &nbsp;I attached an example circuit. &nbsp;Thanks for any help. &nbsp;<br />

Digital/analog ic switch to choose between capacitors

The Math / Science topic primarily includes discussions of mathematics, physics, statistics and economic analysis, but also biology, chemistry and other sciences.

Math / Science

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.
