AD5452 50K W=0 but 64Ohm?

Question asked by tommib on Dec 22, 2016

Hallo, i use AD5254 50k for a simple Audio mixer. Instead of an analog Poti i set the AD5452.
I wonder, because wenn i set the W on 0 i can hear a Little bit Audio, althoug B is set on GND.
Now i measure a resistor of 64OHm between W and B, when set on 0 .

Why is it so?
