Digital POT AD5175: Does resistance value change with voltage?

Hi I am planning to use ADI digital POT AD5175 for one of my application.

Typical application is to change output voltage of LDO by changing reference resistor divider.

My question is

 

1) Does the value of resistance of AD5175 changes with supply voltage?

For example would the resistance between terminal A and W change if device is used at 3.3V or 5V?

 

2) Datasheet mentions nominal resistance of 10k and 1024-position resolution.

Does this mean that I can change resistance from 0ohm to 10k in ~10ohm steps (10k/1024)?

 

Regards,

Dwijen
