I see that the update rate of the AD5696R is 2.5Msps from the selection Table.
but I don't find the parameter from the data sheet of AD5696R.Could you tell me something about update rate and how
to get it?
Is the 2.5 MSPS requirement per channel (10 MSPS for 4 channels) or for all channels (4) already?
We have some DACs that which can have this update rate but that would be for all channels already, so a 2.5 MSPS DAC for 4 channels will result to a ~625kSPS per channel. The workaround would be to use four different single channel DACs but this would also mean four SPIs.
Second alternative is to use parallel interface, however we do not have a 16-bit, 4 channel DAC as of this moment.
