Hi,In AD5235 Pin description says whenever SDO is used a pullup resistor of 1kto10k has to be used.But to what voltage should this be connected to? 1.8V/3.3V/2.5V/5V???

The pull up is connected to VDD. Please refer to figure 41 in DS.

ok...now VDD is 2.5V but in Table 1,page 4 Vmin for SDO is 4.9...now what to do?
Condition is clearly mentioned in the table. Voh is VDD - 0.1V.
