You may want to consider a newer type device than the 4051. You can anticipate much higher performance, lower ON resistasnce, and more flexible switch configurations. One source for these parts is Analog Devices which has a whole slew of parts in their ADGxxx series. One part I have used in the past is the ADG714. The data sheet is here (ADG714). This part is typical of many in the series in that the control input pins will work properly with normal TLL level inputs. You can run the part on 5V or +/-2.5V voltage range with corresponding input voltage range. Now I know you said that you needed 0-10v input range, but you should consider using a resistor divider to cut your input signal down to the 0-5V range as opposed to having to provide the higher power supply for the 4051 style part. (The divider cannot be all bad becasue if you are running the inputs into an A/D converter you may very well be anticipating the need for an anti-aliasing filter so the divider can be a part of that filter). A last comment I could make would be that a part like the ADG714 has an I²C interface on it so it is very easy to provide a 2-wire interface to the part from the microcontroller. In some applications that can make it much easier to locate the part in the analog section of your board and minimize the number of signals you have to couple across the digital to analog boundary.
