AD5940 - I'm seeing a 6KHz signal 200mV pk-pk signal on the SE, CE, & RE pins with respect to circuit common.
I don't know why.
The only place I've been able to find a reference to a 6KHz signal is in the "AD5940 : Exitation frequency is different from measured frequency" Q&A.
Is this a desired signal, if not, what am I missing to remove it?(working with my PCB, not a development board / does not seem to affect the output reading)
