Trying to figure out what "Iout Full Scale" means on the AD9832. On page 7 of this doc:  http://www.analog.com/media/en/technical-documentation/user-guides/UG-313.pdf  It shows the AD9832 output as 572 mV peak to peak across 300 ohms.  This works out to 1

Trying to figure out what "Iout Full Scale" means on the AD9832. On page 7 of this doc:  http://www.analog.com/media/en/technical-documentation/user-guides/UG-313.pdf  It shows the AD9832 output as 572 mV peak to peak across 300 ohms.  This works out to 1.9 mA peak to peak current through the resistor.  But Rset on the board is 3.9K, which is supposed to give a value for so-called "Iout Full Scale" of 3.878 mA.  I would have thought (just guessing) that peak to peak output current would be equal to Iout Full Scale, but it appears to be only half of that.  Can anyone clarify this?  Rick
