I'm planning a project involving the ADNS-5050 optical mouse sensor package. The data sheet for this package says that it needs to be combined with 4 capacitors, and it has a diagramme that I think is supposed to tell me what capacitors to use, but I don't have a great deal of experience with electronics and don't know exactly how to interpret it.
The relevant part of the diagramme is:
As far as I can tell, the document does not elaborate on these four capacitors. Obviously, the 0.1, 3.3 and 4.7 are measures of capacitance, but I don't know what the units are, or even if they are all the same units. I do recognize from the symbols that two of them are polarized and two are non-polarized, but I am kind of floundering at figuring out what exactly I need to hook up.
What capacitors exactly is this diagramme calling for, and how might I have figured it out by myself? :-)
