Digital potentiometer AD5124 VDD pin connection

Question

Hello, 
 According to the datasheet of AD5124 we can believe that VDD pin is for biasing "potentiometer staff". 
 Given that I need to generate voltages in the range -5V ... 0V , can I bias AD5124 in the following way: 
 
 VDD connect to ground 
 GND connect to ground 
 VSS connect to -5V 
 VLOGIC connect to +5V (or 3.3V) 
 
 Thanks.

Hi, 
 If you will operate on the negative side, GND must be tied to VSS (-5V). Vlogic must also be tied to Vdd (0V). Make sure to produce negative logic levels on digital signals. Thanks!
