i am using AD9912 as the DDS chip.

i have a doubt regarding the output voltage variation in AD9912. the output voltage of the DDS can be changed by varying the IDAC current of the DDS, so how much is the range that i can choose. And instead of using the 10 bit resolution is it posible to handle the resoluition by using the Multiplier and a DAC output? which oen is the best that i can choose? another option is to choose a PGA .

From the above three above techniques which is the best . my range is from 1uF to kHz.
