I would like to use a DDS as a waveform generator with following specs
Output Frequency : 0-15kHz
Voltage Range of output : 0 - 20V
Output Voltage Resolution : 0.393mV
I am looking at the AD9834 I see that the min output voltage is 30mV (across 200ohm resistor) and max is 0.6V I think the max voltage is OK as I can easily scale this. The min voltage of 30mV looks problematic as I need to somehow get the min output voltage to 0V, or as close to it as possible.
Is there some way I can get the output current / voltage down to ZERO?
