High Voltage Digital Potentiometers

I need to use Arduino to control a potentiometer which leads reach about 15 volt. So I decided to use the MCP45HVX1 digital pot. Now I have two questions:

  • What about the wiring? I've found no drawings with referring code samples using the MCP45HVX1.
  • Am I assumed to power the digital pot with a voltage at least the same value of the voltage in the circuit? In this case will Arduino be protected against voltages beyond 5 volt?
    Thanks!

It is a great idea to consult the device data sheet first.

Description:
The MCP45HVX1 family of devices have dual power
rails (analog and digital). The analog power rail allows
high voltage on the resistor network terminal pins.
