Hi Everyone !
I need to built signal generator 10 Hz - 3 KHz. I've decided to use AD9953 DDS IC + AD8138 Differential DAC Driver.
AD9953 has DAC_Rset pin which is connected to AGND through Rset resistance. Rset value determines DAC maximum output current. The question is - Can I use digital potentiometer instaed of Rset resistance to control output amplitude ?
