I'm experimenting with a CMOS analog switch (MAX4662). It's got 4 switches
in it and can be run on +/- or single supply. I'm only using 1 of the
switches at the moment, and I'm running it singel supply. Which of the
remaining pins need to be grounded? I was thinking just the com pins (and
not the NC or NO), but then got wondering about V-.....
The ground and VL pins power the logic section that must
match the voltage swing of the controlling signals. Unused
controls can be tied either to ground of to VL.
V+ and V= power the switches, themselves, and those rails
must contain all analog signals passing through the
switches. VL and Ground must be inside the V- to V+ range.
The unused switch connections (COM, NO, NC) may be left
floating or tied to any voltage between V- and V+.
