AD5290 Digital Potentiometer with dual supply

[drewman2000]

The issue I'm having is that have a AD5290 that needs to be able to have voltages on the A/W/B terminals that go between +-12V. Therefore I currently have Vss connected to the negative 12V rail of my power supply and Vdd is connected to the positive 12V rail. I'm using an Arduino Mega 2560 to send SPI commands and if I want to power the Arduino via the positive 12V rail I can't ground it without causing issues. If I ground it to the common ground of my power supply then whenever I connect the Arduino ground to the digital ground on the AD5290 I short the negative rail of my power supply, any suggestions on a work around?

Shouldn't have any problems.  I've been using the AD5290 for the past year or so and hooked up to a MegaADK.
AD5290 pin 3 to -12
AD5290 pin 4 to digital ground (e.g. 0 volts)
AD5290 pin 9 to +12
MegaADK gets power off the +12v rail thru a regulator.
Works fine.
Let's see your power supply.

Figured it out, bad chip lol. I guess I must have wired it up wrong one of these times and it didn't like it, thanks for the quick response!

I've got 4 AD290's mounted on SMT-DIP adapter boards that I play with from time to time...or rather HAD 4 of them.
Haven't miswired any of them, but still somehow managed to blow the pot out of 3 of them.
Touchy things...
