Don't overlook a bug in the data sheet. The data sheet for the actual part at http://www.analog.com/media/en/technical-documentation/data-sheets/AD9832.pd f says IOUT Full Scale 4 mA nom, 4.5 mA max Output Compliance 1.35 V max 3V supply I didn't find any reference to "peak" on that data sheet, so no peak-to-peak. -- These are my opinions. I hate spam.
