I would like to know how does the output amplitude of the AD9951 DDS change with temperature. I have been searching in the documentation but I could not find anything.
Can anybody help me with this issue?
Thank you in advance.
Unfortunately, the AD9951 was not characterized for output swing vs temperature. However, there's an internal band gap reference used to produce the DAC full scale current. The band gap reference is used to help reduce amplitude flucuations at the output. Note, you could enable and use the output scalar (OSK manual mode) to help compensate for output flucuations once the you've characterizised the device over temperature.
