The datasheet for AD9954 specifies the total power consumption of the device. I would like to know the current taken by the AVdd and DVdd supplies separately. I'm using separate regulators for AVdd and DVdd. Thanks!
Independent AVDD and DVDD power consumption data for the AD9954 is not available at this time. Plans are in place, however, to make these measurements and the results will be posted here on the DDS forum within the next few days.
The attached excel file shows the individual current draw between AVDD and DVDD.
Note, the total power dissipation numbers are a little higher in the AD9954 data sheet.This is due to the power supply conditions of AVDD = DVDD = 1.8V + 5% (1.89V) for the data sheet conditions whereas the data was taken @ 1.8V.
