Hi What is the minimum output frequency supported by AD9834 DDS chip?. I am using 2 MHz as reference clock for AD9834.
The circuitry in the DDS products supports frequencies all the way down to DC (0Hz). The AD9834 has a 28 bit tuning word. If you set the tuning word to 1, then your speed will be Fsam/2^28. For Fsam = 2 MHz, which is about 7.5 mHz.
Can you please elaborate on the tuning word set to 1?.
Please let us know which register to set 1.
Please refer to the data sheet, specific section: Writing To a Frequency Register
I am writing the value of 0A7C value to the register for 20Hz output with 2MHz reference. Can you please whether the value is correct?.
We are getting the output value upto 1KHz from the DDS output correctly.
