AD5203: Negative voltage at the output

Question

Accepted Answer

Question Is it possible to connect a negative voltage to any of the potentiometers 
 outputs (A,B,AGND) in order to achieve a negative voltage at the wiper (W)? I 
 need a voltage range from -5V to 0V. If it is possible, which output(s) have to 
 be connected to -5V? Answer No it is not possible to have a negative voltage at the wiper output because 
 the AD5203 is a single supply device (2.7 - 5.5V) and the potentiometers 
 terminal voltages must be within the supply voltage range. Supply signals 
 present on terminals A, B, and W that exceed VDD or GND will be clamped by the 
 internal forward biased diodes. A better option, if outputs have to be 
 connected to -5v would be to use one of the dual supply devices such as the 
 AD5263.
