I am working on the design of a circuit where some DDS are needed. They will work on the same frequency (range 100 - 600 kHz) and at different phases.


The amplitude must be adjustable. The changes in aplitude would be at low frequency.


The DDS I have chose is the AD9832.


The question is: Can "FULL SCALE CURRENT" of the AD9832 be adjusted using the technique of Circuit Note CN-0156?


NOTE: Never exceeding nominal current (1.21 [V] / 3900 [Ohm] = 0.3 mA).



Thanks for the support!
