DAC104S085-Q1: Maximum supply current at VA pin

Hi Bharathiraja,

Are you asking about the maximum current that the device can tolerate through the VA pin before damage? 

Or the maximum current that the VA pin will source from the supply during device operation?

Hi Katlynne Jones,

We have a ferrite in series on the VA pin in my design. To find the max drop across the filter , I'm looking for the maximum current that the VA pin will source from the supply during device operation.

Thanks,
Bharathiraja

Hi Bharathiraja,

The maximum supply current when the DACs are unloaded is mentioned here in the datasheet:

If your DACs are loaded, you'll need to add this to the supply current. For example, if each output channel is sourcing 1mA, the total current from VA would be the supply current (either 485uA or 650uA depending on your VA voltage) + 4mA.
